This was CNBC's live blog tracking developments in the Israel-Hamas war. Click here for the latest Israel news and updates on Gaza.

The UN Palestinian refugee agency sounded an alarm, saying its aid workers will no longer be able to continue humanitarian operations in the Gaza Strip unless new supplies are allowed into the besieged enclave.

Israel's military continued to urge residents to move from northern Gaza to the south as it pledged to counter Hamas with "an even greater force." The Israel Defense Forces said it would not carry out any military operations along the evacuation route from 10 a.m. local time (3 a.m. ET) to 1 p.m. Sunday.

The evacuation orders have been criticized by many humanitarian agencies, however. After negotiations between Israeli Prime Minister Benjamin Netanyahu and U.S. President Joe Biden, a decision to renew water supplies to parts of southern Gaza was agreed upon, Israel Energy Minister Israel Katz said on Sunday. The UN warned late Saturday that the lack of water and fuel in Gaza had "become a matter of life or death."

Energy Minister Israel Katz said that the decision to partially renew water supplies was in line with Israeli policy, which is to tighten a blockade on the Hamas-ruled territory.

On Sunday, China urged Israel to end its collective punishment of Palestinians in the Gaza Strip, saying that "Israel's actions have gone beyond self-defense." China's Foreign Minister Wang Yi's comments came during a series of weekend calls, as world leaders worked to avert a wider conflict in the Middle East.

Meanwhile, U.S. Senate Majority Leader Chuck Schumer (D-N.Y.) said on Sunday that the Senate would swiftly push through a military aid package to help Israel in its fight against Hamas.

"We will work to move this aid through the senate ASAP, and the Israeli leaders made it clear to us they need the aid quickly," said Schumer during a trip to Israel.

Separately, the U.S. Embassy in Israel said it would help Americans and their immediate family members to depart the northern Israeli port city of Haifa via sea to Cyprus on Monday. "Boarding will proceed in order of arrival and is on a space-limited basis," the embassy said.

U.S. Secretary of State Antony Blinken will head back to Israel after meeting with Saudi Arabia's Crown Prince Mohammed bin Salman on Sunday. The top U.S. diplomat is also expected to land in Egypt later in the day and work on a deal to grant safe passage of Americans currently in Gaza through the Rafah gate — the only crossing between Egypt and the Gaza Strip.

Gaza — a narrow strip of land sandwiched between Egypt, Israel and the Mediterranean Sea — has been pounded by Israeli forces in response to Hamas' brutal attack on Israel last weekend. The death toll continues to tick higher, with at least 1,400 killed in Israel and nearly 2,700 in Gaza. The number of hostages believed to be held by the militants has jumped to 155, according to IDF spokesperson Daniel Hagar.

UNRWA says staff are 'no longer able' to provide humanitarian aid in Gaza

The U.N. Palestinian refugee agency said its staff are "no longer able to provide humanitarian assistance in Gaza."

"Gaza is running out of water, and Gaza is running out of life," the commissioner-general of United Nations Relief and Works Agency for Palestine Refugees (UNRWA) said in a statement Sunday, warning they will soon run out of food and medicine too.

"There is not one drop of water, not one grain of wheat, not a litre of fuel that has been allowed into the Gaza Strip for the last eight days," said Philippe Lazzarini. "An unprecedented humanitarian catastrophe is unfolding under our eyes."

In a statement to CNBC, Israel's Defense Forces said: "Israel has no legal obligation to supply Gaza with electricity, fuel or goods. Gaza is independently capable of generating electricity and supplying water."

The IDF claimed that "90% of Gaza's water is sourced within the Gaza Strip," and blamed Hamas militants for destroying the infrastructure at crossings "through which goods pass through everyday."

The IDF also claimed the militants were diverting resources in Gaza for their own use.

The UNRWA has lost 14 of its staff members and said most of its 13,000 staff in the besieged enclave are now displaced or out of their homes.

"Unless we bring now supplies into Gaza, UNRWA and aid workers will not, be able to continue humanitarian operations," Lazzarini said.

Death toll in Gaza rises to nearly 2,700; Israel's hostage count jumps to 155

The death toll in Gaza has risen to 2,670 and 9,600 people have been wounded, according to Gaza's health ministry, as Israel continues its offensive against Hamas militants in the besieged enclave. Deaths in the occupied West Bank also climbed, with 55 people killed and 1,200 others injured.

In Israel, more than 1,400 people have died while 3,500 were wounded, according to the government press office.

The number of hostages believed to be held by Hamas in Gaza jumped to 155, according to IDF spokesperson Daniel Hagar, who did not confirm if it was due to an increase in civilian abductees or combined military-civilian hostages.

Biden says he's 'shocked and sickened' by brutal killing of 6-year-old Muslim boy

President Joe Biden has called on Americans to "reject Islamophobia," as he condemned the brutal killing of a six-year-old Muslim boy in Illinois.

"As Americans, we must come together and reject Islamophobia and all forms of bigotry and hatred," Biden said in the statement, adding that he and his wife were "shocked and sickened."

Detectives said the boy and his mother were targeted for their Muslim faith by the suspect, 71-year-old Joseph Czuba. He has been charged with first-degree murder, attempted first-degree murder, two counts of hate crime and aggravated battery with a deadly weapon. The suspect is believed to have committed the attack as a result of the Israel-Hamas war.

The child's mother, who suffered multiple stab wounds, is expected to survive the attack that occurred in Plainfield Township, some 40 miles southwest of Chicago on Saturday.

"The child's Palestinian Muslim family came to America seeking what we all seek — a refuge to live, learn, and pray in peace," Biden said. "This horrific act of hate has no place in America."

Israel's ground offensive may 'happen in stages' rather than a full invasion, says former ambassador

Israel's ground invasion could take place in stages rather than a full-scale invasion, said Daniel Kurtzer, a former U.S. ambassador to Israel.

"Israel is not getting any timetable, it could happen any moment. But it could also happen in stages with additional incursions by small groups of Israeli soldiers rather than a full invasion," Kurtzer told CNBC's "Asia Squawk Box."

Israel has been amassing troops along the Gaza border in preparation for a ground offensive in a bid to eradicate Hamas militants. On Friday, the Israel Defense Forces issued a 24-hour notice for 1.1 million residents in northern Gaza to evacuate to the south for their own safety.

He said Israel is still "holding its cards very close" and there could be operational reasons not to go in right away.

"Their bombing and artillery is designed to soften up [the part of] northern Gaza that they may in fact enter," said Kurtzer, who is currently a professor at Princeton University. He added there's also a psychological aspect keeping Hamas on its toes and ensuring that Israel will have some "operational surprise."

China says Israel's actions have 'gone beyond self defense' in Gaza

China urged Israel to heed calls from the international community to end its collective punishment of Palestinians in the Gaza Strip.

"Israel's actions have gone beyond self-defense and it should heed the call of the international community and the Secretary-General of the United Nations to stop its collective punishment of the people in Gaza," China Foreign Minister Wang Yi reportedly told his Saudi Arabia counterpart Faisal bin Farhan Al Saud in a call on Sunday.

Wang's comments came during a series of calls over the weekend, as world leaders worked to prevent an escalation of the Israel-Hamas war into a broader Middle East crisis.

Biden says 'there needs to be a path to a Palestinian state'

U.S. President Joe Biden said in an interview on CBS' "60 Minutes" that he believes Hamas must be fully eliminated and that it is necessary to establish a Palestinian state.

"There needs to be a Palestinian Authority. There needs to be a path to a Palestinian state," Biden said in an interview filmed Thursday, which aired Sunday evening.

The U.S. has historically been one of Israel's biggest allies. But it has also endorsed a two-state solution, which would a separate Palestinian state next to Israel.

Oil prices ease as investors assess impact of Israel-Hamas war

Oil prices eased in early Asia trade on Monday, reversing last Friday's rally as investors waited to see if the Israel-Hamas conflict draws in other countries, which could drive up prices further and deal a fresh blow to the global economy.

Brent futures fell 36 cents, or 0.4%, to $90.53 per barrel and U.S. West Texas Intermediate (WTI) crude dropped 37 cents, or 0.4%, to $87.32 a barrel by 2215 GMT on Sunday.

Both benchmarks rose nearly 6% on Friday, posting their highest daily percentage gains since April, as investors priced in the possibility of a wider Middle East conflict.

Brent also recorded a weekly gain of 7.5%, its biggest such increase since February. WTI climbed 5.9% for the week.

The conflict in the Middle East has had little impact on global oil and gas supplies, and Israel is not a big producer.

But investors and market observers are assessing how the conflict could escalate and what it might mean for supplies from nearby countries in the world's top oil-producing region.

Stock futures edge higher as investors brace for a busy earnings week and new developments in the Middle East

Stock futures inched higher in overnight trading Sunday as markets faced an uncertain week ahead, with earnings season heating up and developments in the Israel-Hamas war leaving investors wary.

Futures tied to the Dow Jones Industrial Average added 0.05%, while S&P 500 futures and Nasdaq-100 futures gained 0.07% and 0.17%, respectively.

Oil prices spiked more than 5% during Friday's session and posted their best day since April as the conflict between Israel and Hamas fueled some fears related to oil production in the region.

Some on Wall Street are bracing for more volatility into year-end as yields and oil prices rise, inflation remains sticky, and conflict ensues in the Middle East, said Eric Johnston, Cantor Fitzgerald's head of equity derivatives and cross-asset.

"This Mideast situation is kind of showing that when you own equities, you are taking risks," he told CNBC's "Closing Bell" on Friday. "As a result, you need to have good upside returns in order to justify that risk, because there are things that come out of nowhere, like this situation."

Over the weekend, Israel's military continued urging residents to evacuate northern Gaza amid a widely anticipated ground invasion. Meanwhile, U.S. Senate Majority Leader Chuck Schumer (D-N.Y.) said Sunday that the Senate would work to quickly push through a military aid package to assist Israel as it battles Hamas.

Man killed Muslim boy and wounded woman in hate crime motivated by Israeli-Hamas war, police say

A 71-year-old Illinois man was charged Sunday with a hate crime, accused of fatally stabbing a young boy and seriously wounding a woman because of their Islamic faith and the Israel-Hamas war, authorities said.

Officers found the 32-year-old woman and 6-year-old boy late Saturday morning at a home in an unincorporated area of Plainfield Township, southwest of Chicago, the Will County Sheriff's Office said in a statement on social media.

The statement added that the boy was pronounced dead at a hospital and the woman had multiple stab wounds and was expected to survive. An autopsy on the child showed he had also been stabbed multiple times.

"Detectives were able to determine that both victims in this brutal attack were targeted by the suspect due to them being Muslim and the on-going Middle Eastern conflict involving Hamas and the Israelis," the sheriff's statement said.

According to the sheriff's office, the woman had called 911 to report that her landlord had attacked her with a knife, adding she then ran into a bathroom and continued to fight him off.

The boy was stabbed numerous times with a knife, according to an autopsy, the sheriff's office said. The woman had more than a dozen stab wounds and remained hospitalized Sunday and was expected to survive.

The Chicago office of the Council on American-Islamic Relations held a news conference later Sunday with a family member and knew their identities. It said text messages exchanged among family members showed the attacker had made disparaging remarks about Muslims.

The Muslim civil liberties organization called the crime "our worst nightmare," and part of a disturbing spike in hate calls and emails since the outbreak of the Israel-Hamas war.

U.S. State Department says 30 Americans killed in Israel, 13 are still missing

The U.S. State Department says the number of Americans killed since the outbreak of war between Israel and Hamas has risen to 30.

"At this time, we can confirm the deaths of 30 U.S. citizens. We extend our deepest condolences to the victims and to the families of all those affected," the State Department said in a statement released Sunday. The U.S. is also aware of 13 missing citizens and has been in contact with their families.

Hamas militants stormed into Israel on Oct. 7 and murdered more than 1,400 Israelis, the vast majority of them civilians. The militants also kidnapped at least 155 people — a number that includes babies and the elderly — and are holding them hostage in Gaza. Their whereabouts are not publicly known, but their families have been urgently pressing for their release.

"The U.S. government is working around the clock to determine their whereabouts and is working with the Israeli government on every aspect of the hostage crisis, including sharing intelligence and deploying experts from across the United States government to advise the Israeli government on hostage recovery efforts," the statement said.

The Gaza Health Ministry said 2,670 Palestinians have been killed so far.

Republican Sen. Lindsey Graham warns Iran against escalating war

Sen. Lindsey Graham, R-S.C., on Sunday warned Iran against escalating the war between Israel and Hamas, NBC News reported.

"I want to applaud President Biden for his strong statement, and support of Israel. I just got off the phone with the Israelis. Their goal is to destroy Hamas in the south and try to save as many innocent Palestinians as possible to prevent escalation north from Hezbollah," Graham said in an interview on NBC News' "Meet the Press" on Sunday.

"Here's my message: If Hezbollah, which is a proxy of Iran, launches a massive attack on Israel, I would consider that a threat to the State of Israel, existential in nature."

Graham said he plans to introduce a resolution in the Senate to "allow military action by the United States in conjunction with Israel to knock Iran out of the oil business," according to NBC News.

"Iran, if you escalate this war, we're coming for you," Graham added.

FBI notes increase in threats against Jewish and Muslim communities

FBI officials say they've noticed an increase in threatening rhetoric targeting both the Jewish and Muslim communities in the week since the brutal Hamas attacks in Israel.

Director Chris Wray said on a call with reporters Sunday that the FBI is moving quickly to mitigate the threats and that the FBI does not discount the possibility that Hamas and other groups could exploit the conflict in the Middle East to call for or plot attacks in the United States.

A senior FBI official who spoke on condition of anonymity under ground rules set by the bureau said the majority of the threats that the FBI has responded to were not judged to be credible. But the official said the FBI takes them all seriously nonetheless.

The official also said that agents have been encouraged to be "aggressive" and proactive in communicating over the last week with faith-based leaders. The official said the purpose of that outreach is not to make anyone feel targeted but rather to ask clerics and others to report to law enforcement anything that seems suspicious.

Besides responding to an escalating number of threats, Wray said the FBI was also working through its legal attache office in Tel Aviv to do what it can to locate and identify Americans who remain unaccounted for after last weekend's attacks.

U.S. State Department says flights out of Israel for Americans will continue Monday and Tuesday

The U.S. Department of State on Sunday announced that the charter flights out of Israel offered to American citizens will continue "on a rolling basis" on Monday and Tuesday.

The State Department set up the flights for U.S. citizens stranded in Israel, unable to leave due to the limited availability of commercial flights out of the country.

"We urge those wishing to leave to take advantage of these charters while they are available," the department said in a statement.

Only U.S. citizens are eligible for the flights and must sign an agreement prior to departure that pledges to repay the U.S. government for the travel. The flights will leave from Israel's Ben Gurion International Airport.

The department also provided details on how U.S. citizens in the Israeli city of Haifa can leave via a 10- to 12-hour ship ride to Cyprus on Monday. Those wishing to take the ship must arrive at Haifa port passenger terminal at 9 a.m. local time on Monday.

The U.S. government is still negotiating how to get American citizens in Gaza out of the region. It had secured a route of safe passage via the Rafah gate border crossing from Gaza to Egypt, but Americans trying to flee reportedly still have not been let through. In the meantime, the government is encouraging Americans in Gaza to fill out a crisis intake form in case they need to be contacted on short notice.

The State Department has issued a "Do Not Travel" advisory for Gaza and "Reconsider Travel" advisories for Israel and the West Bank.

Iranian president warns war could expand if Israel's siege of Gaza continues

Iran's hard-line president spoke with France's leader on Sunday, warning that war would expand if Israel's siege of Gaza doesn't stop, state-run media reported.

The official IRNA news agency said Ebrahim Raisi and Emmanuel Macron spoke over the phone. The Iranian president made no mention of the unprecedented Oct. 7 incursion by Gaza's militant Hamas group into southern Israel that sparked the latest Hamas-Israel war. Iran has long been a supporter of Hamas.

"The situation will be complicated ... if the crimes by the Zionist regime, including the killing of people and blockade of Gaza, are not stopped," Raisi was quoted as saying, referring to Israel. IRNA did not provide further details.

Earlier, the Elysee Palace confirmed this weekend that Macron planned to talk to Raisi to urge Iran not to fuel tensions in the region or provide any operational support to Hamas.

Macron intended to press the argument that bringing the violence to a rapid end is in everyone's interests, including Iran's, the presidential office said. France feels that Iran can play a positive role in the crisis by simply not getting involved in it, either with "words that are unacceptable" or by supporting Hamas.

Over the weekend, Raisi also spoke with leaders of Arab nations of Iraq, Oman and Qatar and urged them to support Gaza's Palestinians, Iranian media said.

He also accused Israel of perpetrating a "genocide" in Gaza and criticized the United States for its support of Israel.

Blinken meets with Egyptian president, reiterates need for 'safe passage' for Americans in Gaza

U.S. Secretary of State Antony Blinken met with Egypt's President Abdel Fattah El-Sisi in Egypt on Sunday to discuss the ongoing Israel-Hamas conflict and how to keep civilians safe amid the violence and lack of humanitarian aid in Gaza.

In the meeting, Blinken brought up the ongoing efforts to get American citizens in Gaza safely out of the region. The secretary had been trying to find a way for Americans to exit Gaza via the Rafah gate into Egypt, but those trying to leave have reported that the border crossing has remained closed.

"Secretary Blinken reiterated to President El-Sisi the importance of facilitating the safe passage of American citizens and family members from Gaza," a spokesperson for Blinken said.

Over the past week, Blinken has been on a Middle East tour, trying to prevent the conflict from spreading throughout the region and to rally humanitarian support for civilians caught in the crossfire of the war.

Blinken has met with officials in Israel, Jordan, Qatar, Bahrain, Saudi Arabia, the United Arab Emirates, and Egypt. The State Department announced that he will return to Israel on Monday.

White House national security advisor says Israel has turned water back on in some parts of Gaza

White House National Security Advisor Jake Sullivan said Israel has reactivated the water pipes in southern Gaza after several days of cutting off the water supply in response to the deadly attack Hamas launched last weekend.

"I have been in touch with my Israeli counterparts just within the last hour who reports to me that they have in fact turned the water pipe back on in southern Gaza," Sullivan said Sunday in an interview on CNN's "State of the Union."

"That has been the subject of discussion over the course of the past few days," he added.

In a series of Sunday interviews, Sullivan reiterated the U.S. stance that all innocent civilians must be protected amid the violence of the Israel-Hamas conflict.

His comments come as many civilians remain trapped in Gaza without access to basic necessities like food, water, medicine and shelter.

"The many, many Palestinians who have had nothing to do with the brutal terrorist organization among us the vast majority of the population of Gaza. They deserve dignity. They deserve safety and security," Sullivan said in an interview on NBC's "Meet the Press."

Sullivan also said the White House is "working actively" to get Americans in Gaza access to safe passage to leave the region, though those evacuation efforts have been thwarted by Hamas.

"So far, we have not been able to get American citizens through the border crossing and I'm not aware of anyone else being able to get out at this time," he said.

"We did not ask for this war, but we will win it," Israeli Defense Forces' Peter Lerner says

IDF spokesperson Lt. Col. Peter Lerner said on Sunday the military plans to strike Hamas from the top through its institutions, "all the way down to the individuals that conducted the butchery of our babies."

"We did not ask for this war, but we will win it," Lerner said on "This Week" on ABC.

He said they've instructed Gazans to evacuate the north "to keep people out of harm's way so that we can deal with Hamas." But he said Hamas was trying to interfere with those efforts.

"They have no regard for human life, Israeli or Palestinian," he said.

Lerner also said that some of its forces have dispersed to communities along the border with Lebanon "in anticipation for a potential uptick in violence with Hezbollah."

Israel urges Gazans south, as airstrikes continue ahead of ground assault

The Israeli military said on Sunday it would continue to allow Gazans to evacuate south ahead of an expected ground assault by its forces on the Gaza Strip in retaliation for unprecedented attacks by Hamas militants eight days ago.

The army said hundreds of thousands had already moved south as Israel carried out the most intense bombardment the enclave has ever seen in response to the killing of 1,300 people in Israel, including 279 Israeli soldiers.

Authorities in Gaza said more than 2,300 people had been killed, a quarter of them children, and nearly 10,000 wounded so far. The enclave's hospitals are running short of medical supplies and struggling to cope with the flow of injured.

Regional WHO chief appeals for the immediate reopening of Eqypt's Rafah border crossing with Gaza

The regional head of the World Health Organization told The Associated Press on Sunday that evacuating hospitals from the northern part of the Gaza Strip is "impossible" and said Israel's demand for the evacuation of medical facilities there goes against international law.

Ahmed Al-Mandhari said 22 hospitals with 2,000 patients in northern Gaza managed to move "mobile patients" to the south over the past two days but most of the patients can't be evacuated.

"It is really very risky, very dangerous if we push these hospitals to evacuate," he said in Cairo.

Egypt has yet to reach an agreement with Israel and Hamas to reopen the Rafah border crossing to deliver medical supplies and other humanitarian aid territory to the besieged, Hamas-ruled strip.

Al-Mandhari urged for the reopening "immediately, with no delay." The U.N. health agency has supplies waiting in Egypt, around 20 kilometers (12 miles) from the Rafah crossing but cannot take them inside, he said.

Rafah was shuttered early on Tuesday after Israeli airstrikes hit close to Gaza's side of the crossing.

Egypt's President Sisi in talks to get aid to Gaza, presidency says

Egypt's president Abdel Fattah al-Sisi is in talks with international and regional partners to enable aid deliveries into Gaza and to de-escalate the fighting there, his office said on Sunday.

Israeli bombardments on the Gaza side of the Rafah crossing into Egypt, the main crossing out of Gaza not controlled by Israel, have disrupted operations there.

Aid from several countries has been building up in Egypt's Sinai peninsula due to a failure to reach a deal enabling its safe delivery to Gaza and enabling evacuations of some foreign passport holders through the Rafah crossing into Egypt.

U.N. aid chief Martin Griffiths said on Saturday that the humanitarian situation in Gaza is "fast becoming untenable".

The statement from Sisi's office also said Egypt rejected any plan to displace Palestinians "to the detriment of other countries," and said Egypt's own security was a red line.

Sisi also proposed a summit to discuss the crisis, according to the statement.

Blinken will return to Israel after stops in Arab nations aimed at avoiding a broader conflict

U.S. Secretary of State Antony Blinken will return to Israel this week after completing a frantic six-country rush through Arab nations aimed at preventing the Israel-Hamas war from igniting a broader regional conflict.

The U.S. State Department announced Blinken's plan to travel Monday to Israel — his second visit in five days — as America's top diplomat arrived in Cairo for talks Sunday with Egypt's president, Abdel Fattah al-Sisi. It was the last of Blinken's meetings with Arab leaders amid increasing fears that an impending Israeli ground offensive into Gaza could spark a wider war with devastating humanitarian consequences.

Department spokesman Matthew Miller told reporters traveling with Blinken that the secretary was returning to Tel Aviv "for further consultations with Israeli officials." Miller did not elaborate.

Before landing in Egypt, Blinken met on Sunday morning with Saudi Crown Prince Mohammed bin Salman in Riyadh. That meeting followed talks over the previous three days with the leaders of the United Arab Emirates, Bahrain, Qatar, Jordan and the Palestinian Authority.

Pope Francis renews his call for the release of Israeli hostages held by Hamas

Pope Francis on Sunday renewed his call for the release of Israeli hostages held by Gaza's militant Hamas rulers and called for humanitarian corridors to help those under siege in Gaza.

"I continue to follow with much sorrow what is happening in Israel and Palestine," Francis said during his Sunday's Angelus prayer in St. Peter's Square. "I think back to the many people, especially the little ones and the elderly."

The Pope reiterated his appeal for the release of scores of Israeli hostages snatched during Hamas' deadly incursion into southern Israel last weekend and taken to Gaza.

"I strongly ask that the children, the elderly, women and all civilians don't become victims of the conflict," Francis said. He added that humanitarian law must be respected, "especially in Gaza where there is an urgent need to guarantee humanitarian corridors and to rescue the entire population."

The Pope appealed for the world not to "shed any more innocent blood, neither in the Holy Land, nor in Ukraine, nor anywhere else. Enough! Wars are always a defeat, always."

Thousands march in Moroccan capital in support of Gaza Palestinians

Thousands took the streets of the Moroccan capital on Sunday to rally in support of Palestinians in Gaza and denounce Israel's actions in the latest war with Gaza's militant Hamas rulers.

Waving Palestinian flags, the rally also marked a major showing for the banned Islamist movement Al Adl Wa Ihssane, which supports Hamas. After Hamas's unprecedented and deadly Oct. 7 incursion into Israel, Morocco issued a statement condemning the violence. Royal Air Maroc, temporarily cancelled flights from Casablanca to Tel Aviv — a route that began in 2021.

Demonstrators marched in central Rabat and threw smoke bombs and fireworks as riot police stood between them and the Parliament building and other landmarks.

Hassan Ait Amar, a 52-year-old from Casablanca, carried a sign demanding Morocco's lawmakers revoke a normalization of ties with Israel.

"If they want peace, they (Israel) should respect Palestinians, international law and a two-state solution," he said.

Israel and Morocco normalized relations as part of the 2020 Abraham Accords, a series of diplomatic agreements between Israel and four Arab countries brokered by then-President Donald Trump. Israel is home to a large community of Jews of Moroccan descent. Morocco and Israel have agreed to military cooperation and boosted trade.

EU to hold emergency meeting on Tuesday to discuss Israel-Hamas war

The European Union on Tuesday will hold an extraordinary meeting of its member states to discuss the fallout of the escalating Israel-Hamas conflict and the potential consequences for the bloc.

European Council President Charles Michel said in an invitation letter issued Saturday that it was of the "utmost importance" to establish a "clear unified course of action that reflects the complexity of the unfolding situation."

"If we are not careful, it has the potential to exacerbate tensions between communities and feed extremism" in the European Union, Michel said.

"There is a major risk of migration and movements of a large number of people to neighboring countries which already have a significant number of refugees on their territory. If not handled carefully, there is a risk of onward migratory waves to Europe," he added.

UK wants to minimize Palestinian and Israeli casualties, foreign minister says

British Foreign Minister James Cleverly says he has not specifically asked Israel to wait until Palestinian civilians have moved to the south of Gaza before carrying outs its expected military operation.

"I haven't asked that specific request because Hamas are trying to prevent people leaving northern Gaza," Cleverly told the BBC Sunday morning.

"Of course, we want to minimize Palestinian casualties, we want to minimize Israeli casualties. We want everybody to respect civilians, but the real clear distinction is Israel are trying to get civilians out of danger, Hamas are trying to put civilians into danger and that is a fundamental difference between the two," he added.

The Palestinian militant group of Hamas, which rules the Gaza Strip, has told citizens to ignore Israel's evacuation order. The United Nations has said the evacuation order is not possible and warned of "devastating humanitarian consequences."

Israeli military says Lebanese border is now 'strictly' off-limits

The Israel Defense Forces said it has isolated the area within 4 kilometers (2.5 miles) of the country's border with Lebanon.

IDF spokesperson Rear Admiral Daniel Hagari said the move was taken in response to shooting from Lebanon at Israeli territory.

"Following the assessment of the situation and the shooting incident in the north, it was decided to isolate the area of ​​up to four kilometers from the northern border with Lebanon," Hagari said on X, formerly known as Twitter, according to a Google translation.

"The IDF clarifies that entering the area is strictly prohibited and asks the public to be vigilant and not to enter the area."

He added that the Israeli military was undertaking "proactive GPS jamming" in the area, which could affect location-based apps.

The president of the Committee to Protect Journalists (CPJ), a U.S. non-governmental organization that promotes press freedom, said the last week has been the deadliest on record for journalists covering Israel-Palestine.

As of Saturday, 12 journalists had been killed, eight were injured and two were missing over the course of the first eight days of the Israel-Hamas war, the CPJ said in an update via its website.

Of the journalists confirmed to have been killed, the CPJ said 10 were Palestinian, one was Israeli and a Beirut-based journalist was killed during a shelling attack in southern Lebanon.

"This is the deadliest week ever for journalists covering Israel-Palestine in the more than 30 years that @pressfreedom has been covering attacks on the press," Jodie Ginsberg, president of the CPJ, said Saturday via X, formerly known as Twitter.

UN agency calls for protection of civilians in its shelters, including those in northern Gaza

The United Nations Relief and Works Agency for Palestine Refugees in the Near East called on Israeli authorities to protect all civilians in its shelters across the Gaza Strip, including those in northern Gaza and Gaza City.

The UNRWA warned that despite Israel's order to evacuate the north, many people will not be able to flee, particularly pregnant women, children, the elderly, and people with disabilities.

"UNRWA shelters in Gaza and northern Gaza are no longer safe. This is unprecedented," it said.

"This war should be no exception, protection of civilians and civilian infrastructure, including United Nations buildings, applies to this conflict too."

Israel has ordered roughly 1 million residents in northern Gaza to evacuate to the south ahead of an anticipated ground offensive.

Separately, the UNRWA warned that 2 million people are at risk as water runs out in Gaza and called for humanitarian supplies to be let in. It said its newly relocated base in the south is also running out of water as it takes in refugees, thousands of whom it said followed the evacuation order.

UNRWA Commissioner-General Philippe Lazzarini said fuel needs to be brought in immediately to guarantee safe drinking water.

"If not, people will start dying of severe dehydration, among them young children, the elderly and women. Water is now the last remaining lifeline. I appeal for the siege on humanitarian assistance to be lifted now," he said.

Deal to allow Americans out of Gaza through Rafah gate faces obstacles, officials say

The tentative agreement to grant Americans in Gaza safe passage into Egypt through the Rafah gate continues to face significant obstacles to implementation, U.S. officials told NBC News.

Previous discussions between Egypt, the U.S., Qatar and Israel looked set to allow Americans across the border crossing during a five-hour window Saturday, but NBC reports the deadline came and went without any immediate sign of success. One official told NBC the parties are continuing to negotiate.

Secretary of State Antony Blinken is expected to land in Cairo on Sunday and the deal is set to be a key issue on his agenda.

While sticking points remain, the State Department has urged the estimated 500 to 600 Americans in Gaza to move south, warning that if the crossing opens, the window could be brief.
