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

A first batch of hostages abducted by Hamas on Oct. 7 has been released under the new Gaza cease-fire deal.

President Joe Biden said during a televised address Friday afternoon that "pause in fighting is critical to get humanitarian aid to Gaza." He said that he expected more hostages to be released in the coming days. He added that he thought the chances of an extension of the ongoing truce were "real."

Local TV stations showed 13 Israeli hostages being transferred to the Red Cross, then crossing over into Egyptian territory. Shortly beforehand, Thailand's Prime Minister Srettha Thavisin said that Hamas had also released a number of Thai nationals held captive in Gaza.

Qatar confirmed that a total of 24 hostages held by Hamas in Gaza had been released in two separate deals.

This comes after the first limited pause in fighting formally began earlier on Friday. A number of Palestinian people detained by Israeli forces were also allowed to return home.

It remains to be seen whether both sides — unequivocal in their condemnations of each other until the last moment — will adhere to the terms of the agreement. The long-anticipated pause in the fighting is due to last four days.

Avichay Adraee, an Israel Defense Forces spokesperson, stressed that "the war is not over yet." "The humanitarian pause is temporary. The northern Gaza Strip is a dangerous war zone and it is forbidden to move north."

Biden thanks Qatar, Egypt and Israeli leaders for deal to release hostages, says only a start

President Joe Biden praised U.S. diplomacy behind Friday's release of 24 hostages held by Hamas fighters, saying it was the start of what he expected would be further hostage releases by the Palestinian militant group in the coming days.

"Beginning this morning, under a deal reached by extensive U.S. diplomacy, including numerous calls I've made from the Oval Office to leaders across the region, fighting in Gaza will halt for four days," Biden told a news conference.

Biden declined to speculate about how long the Israel-Hamas war would last, but said he thought the chances of an extension of the ongoing truce were "real." He also expressed hope that American nationals held by Hamas would be freed.

"I don't know how long it will take," Biden said.

"My expectation and hope is that as we move forward, the rest of the Arab world and the region is also putting pressure on all sides to slow this down, to bring this to an end as quickly as we can."

Hamas fighters released 24 hostages on Friday during the first day of the war's truce -- including 13 Israeli women and children, 10 Thai farm workers and a Filipino -- after guns fell silent across the Gaza Strip for the first time in seven weeks.

The hostages were transferred out of Gaza and handed over to Egyptian authorities at the Rafah border crossing, accompanied by eight staff members of the International Committee of the Red Cross (ICRC) in a four-car convoy, the ICRC said.

Biden says size of next group of hostages to be released will be known in next hour

President Joe Biden said in the next hour the size of the next batch of hostages will be known — adding that the U.S. doesn't know the locations and conditions of all of those being held by Hamas.

"In the next hour or so, we'll know what the second wave of releases are and I'm hopeful," Biden said.

'We are committed to the return of all our hostages,' Netanyahu says

Israeli Prime Minister Benjamin Netanyahu declared that he is committed to seeing that all hostages are returned, calling it a goal of the war.

"We have now completed the return of the first of our hostages," the Israeli Prime Minister said in a statement. "Children, their mothers and other women. Each and every one of them is a whole world. But I emphasize to you — the families, and to you — the citizens of Israel, we are committed to the return of all our hostages."

"This is one of the goals of the war and we are committed to achieving all the goals of the war," he continued.

Qatar confirmed Friday that 39 Palestinians held in Israel were freed as part of a prisoner swap arrangement with Hamas.

"We also confirm the release of 39 women and children detained in Israeli jails thus upholding the commitment of the first day of the agreement," a spokesperson for Qatar's foreign ministry said in a social media update following the first phase of the deal.

Qatar confirms 24 hostages have been freed

Qatar confirmed Friday that a total of 24 hostages held by Hamas in Gaza had been released in two separate deals.

Thirteen Israelis were released under one deal, while 10 Thai nationals and one Philippines national were freed under a separate agreement. Early reporting suggested 12 Thai nationals had been released.

"We confirm that the Red Cross has received 24 civilians detained in the Gaza Strip, including a number of civilian women and children, within the framework of the humanitarian truce agreement," a spokesperson for Qatar's foreign ministry said in a social media post.

"Those released include 13 Israeli citizens, some of whom have dual citizenship, in addition to 10 Thai citizens and a Filipino citizen," a separate post said.

Red Cross confirms it has facilitated first phase of hostage release pact

The International Committee of the Red Cross (ICRC) confirmed that its team has begun facilitating the release of hostage held by Hamas in Gaza.

"It's a tremendous relief that after enduring weeks of distress, they can finally reunite with their families," the ICRC's account for Israel and the Occupied Territories said in a post on social media.

Released Thai hostages cross the border into Israel

The twelve Thai hostages released by Hamas have now crossed into Israel, Israeli news outlet Haaretz reported Friday.

The identities of the captives have not yet been released, though they are all reported to be men. CNBC could not independently verify the reports.

The release differs from the exchange of 13 Israeli women and children which also occurred Friday.

Released hostages cross into Egypt

Twenty-five hostages released by Hamas have been transferred from Gaza to Egypt via the Rafah crossing, Egyptian officials said Friday.

The transfer was made moments after the 13 Israeli and 12 Thai captives were freed at around 4:30 p.m. local time.

The 13 Israelis were initially handed over to the Red Cross under a Qatar-brokered deal, which also stipulated a four-day humanitarian pause. The release of the Thai nationals, which was confirmed by the country's prime minister, is understood to be part of a separate arrangement.

Israeli captives transferred to the Red Cross

Thirteen Israeli hostages abducted by Hamas have now been transferred to the Red Cross, according to NBC, as part of a broader four-day truce deal.

The exchange took place at roughly 4:30 p.m. local time, after a humanitarian pause in fighting was implemented at 7 a.m. earlier on Friday, under the terms of the same agreement. It was initially disclosed that the Friday swap would see 13 captives released by Hamas in exchange for the freedom of 24 women and 15 teenage boys from Israeli custody.

Moments before the handover, Thailand's prime minister said that Hamas had released 12 Thai nationals held by Hamas, in addition to the 13 Israeli detainees.

A White House official has said Washington does not anticipate any U.S. citizens will be part of the first batch of hostages released, but remains hopeful that Americans will be among those set free over the coming days.

At least 50 people captured by Hamas during the terror attacks of Oct. 7 and 150 Palestinian individuals imprisoned will be released during the truce period, which is expected to also allow the entry and distribution of additional humanitarian aid for the embattled Gaza Strip, as well as the southward evacuation of Palestinian people from the north of the enclave.

The leader of the Hamas politburo has said that the Palestinian militant group is prepared to observe the terms of the limited armistice, as long as Israel does as well.

An extension of the agreement is so far unlikely, with Israeli officials emphasizing that the war campaign is not yet over despite the brief cessation of hostilities, in the days since the deal was first announced.

Thailand's PM says 12 Thai nationals released by Hamas

Thailand's prime minister said Friday that Hamas has released 12 Thai nationals held captive in Gaza.

In a post on social media, Srettha Thavisin said that embassy officials will collect the hostages within the coming hour. The identities of those released has not yet been revealed.

Hamas did not immediately comment on the announcement.

It comes as 13 further hostages are due to be released Friday in the first stage of a Qatar-brokered deal to exchange a group of women and children abducted by Hamas with Palestinian civilians imprisoned by Israel.

Hamas politburo leader reassures the group will honor the truce as long as Israel does

Ismail Haniyeh, leader of the Hamas politburo, on Friday said that the Palestinian militant group is committed to the humanitarian truce and hostage exchange agreed earlier in the week, provided Israel is as well.

The comments were reported by Reuters.

Hamas had earlier in the day said that Haniyeh would give a speech, according to a Google-translated Telegram update.

Hopes have mounted that Hamas and Israel will observe the terms of the four-day truce and hostage swap, which would mark the first de-escalation in a war that has ravaged Israel and the Gaza Strip since Oct. 7. The concession is only a temporary step, with Israeli officials previously expressing the war is not over despite this brief cessation of hostilities.

The WHO is 'extremely concerned' over welfare of remaining patients at Al-Shifa hospital

The World Health Organization is "extremely concerned" over the safety of patients remaining at the stormed Al-Shifa hospital in the Gaza Strip, amid ongoing evacuation efforts.

"We're extremely concerned about the safety of the estimated 100 patients and health workers remaining at Al-Shifa," said WHO spokesperson Christian Lindmeier, in comments reported by Reuters.

The WHO, U.N. and Palestine Red Crescent Society have been organizing evacuations of medical facilities in the Gaza Strip, which have depleted their fuel, medicine and food supplies and are no longer able to function in a hospital capacity. Patients are being taken to medical complexes in the south of the Gaza Strip, which is not as exposed to bombardment.

Two evacuations have been carried out at the Al-Shifa hospital, with a first effort on Sunday retrieving 31 premature babies, who could no longer receive critical care from depowered life support machines at the facility. The second evacuation removed 190 patients and their companions earlier in the week.

Israeli military shows images of welcome reception for hostages

The Israel Defense Forces have released video footage of the welcoming preparations for the anticipated handover of 13 Israeli hostages held by Hamas, due at 4 p.m. local time.

Among necessities such as medical provisions and fresh clothes, the army has also laid out toys.

"After the initial reception and medical treatment, they will continue to hospitals where they'll be reunited with their families," the IDF said.

The first batch of Israeli hostages is expected to be exchanged for 39 Palestinian women and teenage boys, who were imprisoned in Israel.

First batch of Palestinian prisoners begin move in preparation for release in two hours

A first group of Palestinian prisoners are leaving Damon and Megiddo prisons in northern Israel and are in the process of being transferred to the Ofer military jail in the occupied West Bank, the Israel Prisoner Service told NBC News.

This marks a preparatory step toward the release of a first batch of hostages of Israeli and Palestinian civilians under a swap agreement struck between Israel and Palestinian militant group Hamas. Under the deal, which includes a four-day truce, a total of 50 hostages abducted by Hamas on Oct. 7 will be traded in for 150 jailed Palestinian people.

The exchange of Friday, due to take place in under two hours at 4 p.m. local time, will see the release of 39 Palestinian prisoners — 24 women and 15 teenage boys.

Turkey's Erdogan criticizes Israeli offensive in Gaza Strip

Turkish President Recep Tayyip Erdogan retained a sharp tone against Israel, accusing the country of "war crimes" in its treatment of Palestinian civilians, hours after the start of a truce in the Gaza Strip.

"Israel, which commits a war crime by cutting off electricity, water and food, is trying to prevent the oppression of the people in Gaza from being heard by cutting off their communication with the outside," Erdogan said in a video message sent to the International Strategic Communication​​​​​​​ Summit in Istanbul, according to Turkish state news media Anadolu.

Erdogan has been scathing in his criticism of Israel throughout its offensive in the Gaza Strip, pronouncing it a "terror state" for its impact on Palestinian civilians. The Turkish leader has deployed several humanitarian convoys to deliver aid to the Gaza enclave.

Palestine Red Crescent Society says it has received supplies and aid

The Palestine Red Crescent Society said on social media that it received two ambulances and 85 trucks carrying aid from the Egyptian Red Crescent branch.

The trucks brought in supplies such as food, water, medical equipment, and medication.

Humanitarian assistance has been coming in through the Rafah crossing that borders Egypt, amid rising hopes that the four-day temporary truce agreed between Israel and Hamas will allow more relief resources to come in and be safely distributed across the embattled Gaza Strip.

Israeli military says it has finished preparations to receive hostages

The Israel Defense Forces said they have completed preparations to receive the first set of hostages due to be returned to Israel from the Gaza Strip later on Friday.

"As part of the preparations, the IDF has readied several locations dedicated to the initial reception of the released hostages, including with necessary medical provisions and support," the force said on Telegram. "After the initial reception and medical treatment, the released hostages will continue to hospitals, where they will be reunited with their families."

Under an agreement with Hamas, Israel will receive 13 captives held by the Palestinian militant group on Friday, in exchange for 39 Palestinian civilians that were detained by Israel. A total of 50 hostages abducted by Hamas and 150 Palestinian people held by Israel are due to be swapped over the course of a four-day truce.

More than a million displaced civilians now in U.N. shelters in the Gaza Strip, report says

More than a million internally displaced people (IDP) are now sheltering at facilities in the Gaza Strip run by the U.N. Relief and Works Agency for Palestine, the organization said in a Thursday report based on figures valid as of Nov. 22.

"The average number of IDPs per shelter has surpassed 9,000, indicating a significant level of overcrowding considering that the standard shelter capacity is up to 2,000 people," the agency said. "On average UNRWA shelters are hosting four and a half times more IDPs than their intended capacity."

Bombardment and Israeli evacuation instructions have prompted hundreds of thousands of Palestinian civilians to flee their homes, largely heading toward the south of the Gaza Strip. UNRWA has repurposed many of its school facilities to offer shelter.

Ambulances set off to evacuate Al-Ahli hospital

Ten ambulances of the Palestine Red Crescent Society set out on Friday to evacuate wounded and sick civilians from the Al-Ahli Baptist Hospital in Khan Yunis, the PRCS said on social media.

The effort is a joint venture with the U.N.

The PRCS, U.N. and the World Health Organization have been carrying out operations to evacuate civilians stranded in collapsed, bombarded or blockaded hospitals and move them in facilities in the south of the Gaza Strip or in Egypt.

Earlier this week, the PRCS participated in a second evacuation at the Gaza enclave's largest medical facility, the formerly functional Al-Shifa hospital.

Palestinian civilians freed on Friday to comprise women and teenagers

Israel will release 39 Palestinian prisoners on Friday as part of a captive swap and humanitarian pause agreement struck between the country and Hamas, Qadura Fares, Palestinian commissioner for prisoners, told Reuters.

The Palestinian civilians due to be returned their freedom will comprise 24 women and 15 male teenagers.

These inmates will be handed over to the International Committee of the Red Cross at Israel's Ofer military jail at around 4 p.m. local time, when 13 Israeli hostages held by Hamas are also due to be released.

"After the Red Cross receives the (Palestinian) prisoners, the ones from Jerusalem will go to Jerusalem and the ones from the West Bank will gather in Betunia municipal council where their families will be waiting," Fares told Reuters.

A combined 50 hostages from Israel and 150 Palestinian detainees will be exchanged by the two sides over the course of a four-day cessation of violence that came into effect earlier on Friday. The terms are part of a deal struck between Israel and the Hamas under the auspices of Qatari, Egyptian and U.S. mediation.

Israeli military says it killed Hamas naval commander

The Israel Defense Forces said that they killed the commander of naval forces in Khan Yunis, Amar Abu Jalalah, alongside another operative of the Palestinian militant group in an airstrike.

CNBC could not confirm the IDF social media report.

The Israeli military has set out dismantling Hamas and eliminating its command force as one of the key objectives of its war campaign in the Gaza Strip, along with the release of hostages held by the militants. The IDF has claimed to have killed multiple senior commanders and agents of Hamas to date.

Aid trucks arrive in Gaza Strip under deal terms, Israeli agency says

Aid trucks have begun to enter the Gaza Strip as part of the cease-fire and hostage release deal between Israel and Hamas.

Four tankers of fuel and four of cooking gas were transported from Egypt to U.N. humanitarian aid organizations through the Rafah crossing, the Israeli agency for the Coordination of Government Activities in the Territories said on social media.

The supplies are exclusively intended to help operate essential humanitarian infrastructure in the Gaza enclave, COGAT noted.

"This was approved by the government of Israel as part of the pause and the framework for the release of the hostages agreed with the United States and mediated by Qatar and Egypt," the agency said.

Hamas official says 200 of the hostages held are Israel soldiers

The number of captives held by Palestinian militant group Hamas could be slightly higher than previously estimated by Israel.

In a Sky News interview, senior Hamas official Basem Naim said the group's armed unit, the al-Qassam brigades, have conveyed that roughly 200 Israeli soldiers were abducted during the terror attacks of Oct. 7, along with roughly 50-60 civilians comprising women, children and foreigners.

He said, however, that the concrete numbers were difficult to tally, because of ongoing Israeli bombardment and because of the number of Hamas groups holding hostages.

Israel had estimated 240 captives were detained by Hamas.

"We need security conditions so that it is safe to release them," Naim said, confirming that 50 of the hostages would be returned in exchange for 150 of Palestinian civilians detained by Israel, over the course of a brokered four-day humanitarian pause in fighting.

He refuted claims that the Israel Defense Forces had discovered weapons and militarily purposed tunnels at the Al-Shifa hospital in the Gaza Strip, saying Israel had yet to prove its allegations. The IDF has supplied multiple clips and photos as evidence since its incursion at the Al-Shifa hospital. CNBC could not independently verify the materials.

'War is not over yet,' Israeli military spokesperson says

Fighting between Israel and Palestinian militant group Hamas has only temporarily suspended, an Israel Defense Forces spokesperson stressed, urging Palestinian civilians to continue southward evacuations of the embattled north of the Gaza Strip.

"The war is not over yet," Avichay Adraee said, according to an IDF social media update. "The humanitarian pause is temporary. The northern Gaza Strip is a dangerous war zone and it is forbidden to move north."

He went on, "For your safety, you must remain in the humanitarian zone in the south."

Israel has accepted a four-day limited truce as a component of an extensive hostage release deal, but officials have so far emphasized that the brief halt in fighting does not currently represent the start of a more lasting peace.

Temporary cease-fire comes into effect

The first limited pause in fighting formally began earlier on Friday, the child of long diplomatic labor that will see a first batch of 13 hostages abducted by Hamas on Oct. 7 released later in the day. A number of Palestinian people detained by Israeli forces will be allowed to return home, in kind.

It remains to be seen whether both sides — unequivocal in their condemnations of each other until the last moment — will adhere to the terms of the agreement.

Sirens were still sounding within the first few hours of the freshly brokered peace, according to two updates from the Israel Defense Forces on Telegram.

The Israeli military further said it "completed its operational preparations according to the combat lines of the pause," winding down its campaign after a spate of eleventh-hour fighting. The force said that prior to the cease-fire coming into effect, earlier this morning, it destroyed a tunnel it claims was present at the Al-Shifa medical complex, once the largest functional hospital in the Gaza Strip, and said it continued to hit "terror targets" — which CNBC could not independently verify.

In the Gaza Strip, militant group Hamas on Thursday called for the truce, painstakingly brokered by Qatar, Egypt and the U.S., to allow for extensive humanitarian aid deliveries, including food, medical supplies necessary to restart 26 of the enclave's now resource-depleted hospitals and critical fuel supplies to operate hospitals, pumping wells and sewage facilities, according to a Google translation of a Telegram post.

Here are the details of the Israel-Hamas hostage deal

Israel and Hamas have agreed to a pause in fighting in Gaza to allow for the release of 50 hostages held by the militant group in exchange for 150 Palestinians held in Israeli prisons and also to allow for more aid to enter the enclave.

What are the details?

Under the deal, the two sides agreed to a four-day truce so that 50 women and children under the age of 19 taken hostage could be freed in return for 150 Palestinian women and teenagers in Israeli detention.

The 50 hostages, among about 240 taken by Hamas in their Oct. 7 raid on Israel, are expected to be released in batches, probably about a dozen a day, during the four-day ceasefire.

Sides to the deal have called the break in hostilities "a humanitarian pause". The pause will be extended by a day for each additional batch of 10 hostages released, Israel said in a statement.

Hamas said Israel had agreed to halt air traffic over the north of Gaza from 10 a.m. (0800 GMT) until 4 p.m. (1400 GMT) each day of the truce and to halt all air traffic over the south for the entire period. The group said Israel agreed not to attack or arrest anyone in Gaza, and people can move freely along Salah al-Din Street, the main road along which many Palestinians have fled northern Gaza where Israel launched its ground invasion.

Qatar's chief negotiator in ceasefire talks, Minister of State at the Foreign Ministry Mohammed Al-Khulaifi, said that under the deal there would be "no attack whatsoever. No military movements, no expansion, nothing." He said Qatar hoped it would "be a seed to a bigger agreement and a permanent cease of fire."

Who are the hostages being released?

Hamas has not released a full list of names of those being held in Gaza. A U.S. official said the group had said it needed a pause "to locate and determine where people are". Not all the hostages taken on Oct. 7 were being held by Hamas fighters.

Among the 50 women and children under the age of 19 being released by Hamas are three U.S. citizens, including a girl who turns 4 on Friday, the U.S. official said.

Who negotiated the deal?

Qatar played a large mediation role. Hamas has a political office in Doha and the Qatari government has kept channels of communication open with Israel, even though unlike some other Gulf Arab states it has not normalised ties with Israel.

The United States also played a crucial role, with U.S. President Joe Biden holding calls with Qatari Emir Sheikh Tamim bin Hamad Al Thani and Israeli Prime Minister Benjamin Netanyahu in the weeks leading up to the deal.

Egypt, the first Arab state to sign a peace deal with Israel and which has long played a mediation role over the decades of the Israeli-Palestinian conflict, was also involved.

Israel's economic growth to slow to 2% in 2023 due to war, finance ministry says

Israel's economy is expected to grow 2% in 2023, down from a prior estimate of 2.7%, the Finance Ministry said on Thursday citing the effects of Israel's war with Hamas.

For 2024, the ministry projected growth of 1.6% as its main estimate based on a war that will continue through the year but with the most intense fighting ending in the first quarter and largely contained to the southern border with Gaza.

But a more rapid recovery from the war that would end in early 2024 could lead to growth of 2.2% while a war that continues into 2025 and a slower recovery would mean stagnant growth of just 0.2%.

It noted that prior to the war it was set to raise its 2023 forecast to 3.4%, and the war's impact would be 1.4 percentage points.

The main factor weighing on growth, the ministry said, is poor consumer sentiment that will likely translate into largely flat private spending, Israel's main growth driver, while exports look to dip 0.6% this year.

The economy grew 6.5% in 2022.

"The war situation is characterized by particularly high levels of uncertainty, but its impact on the economy goes beyond any security incident experienced by the State of Israel during the last two decades," said a report from the ministry's chief economist's office ahead of discussions to update the state budget for 2023 and 2024.

Former British PM expresses hope that humanitarian deal 'can be delivered'

Recently appointed British Foreign Minister David Cameron expressed hope that a hostage release and humanitarian deal agreed between Israel and Hamas "can be delivered," according to a Google-translated readout from the Israeli prime minister's office.

"Today, obviously, it's important we talk about this potential humanitarian pause. I think it's an opportunity to crucially get hostages out and to get aid into Gaza. There's never an excuse for this sort of hostage taking. All the hostages should be released," Cameron said.

"I hope everyone who's responsible and behind this agreement can make it happen, to bring relief to those families, including, of course, there are British nationals who have been taken hostage. And so that, let's hope that that can be delivered. "

Cameron was in Israel on Thursday, in a trip that included a visit to the Kibbutz Be'eri community, one of the sites ravaged by the Hamas terror attack of Oct. 7.
