As per the agreed commitment, the Palestinian fighters group, Hamas, released the third group of 13 Israelis in exchange for its 14 citizens and three foreigners taken hostage by Israel on Sunday.
AFP reported that both sides handed over their hostages to the Red Cross in the Gaza Strip as the Israeli army confirmed this exchange and said another four hostages were also en route.
A four-year-old American girl is safely in Israel after being released Sunday from captivity in Gaza, US President Joe Biden said as he urged the pause in Israel-Hamas fighting be extended to allow for more hostage releases.
"She's free and she's in Israel now," Biden said in a hastily arranged appearance before the media after the Israeli army announced that 17 hostages were being freed by Hamas.
"She's been through a terrible trauma," Biden said of four-year-old Abigail, whose parents were murdered by Hamas militants when members of the Islamist group attacked Israel on October 7.
Israeli army says 13 released hostages back in Israeli territory, 4 more en route
The Israeli army said Sunday that 13 released hostages were back on Israeli territory, and another four were on their way to Egypt.
Twelve were headed to a military base, accompanied by Israeli special forces, it said in a statement, and one had been flown directly to hospital. Four additional released hostages were on their way to the Rafah crossing between the Gaza Strip and Egypt, it added.
Israeli army says 14 Israeli hostages, 3 foreigners handed to Red Cross in Gaza
Fourteen Israeli hostages and three foreign nationals were handed over to the Red Cross in the Gaza Strip on Sunday, the Israeli army said.
"Based on information that was received from the Red Cross, 14 Israeli hostages and three foreign hostages have been transferred to the Red Cross," it said in a statement on the third day of an agreed pause in the fighting between Israel and Hamas, that is to also see Palestinian prisoners freed in Israel.
In Gaza, Netanyahu tells troops: 'We continue until victory'
On the other hand, Israeli Prime Minister Benjamin Netanyahu on Sunday made his first to Gaza since the Israel-Hamas war began, telling soldiers there that Israel will continue until it wins.
"We continue until the end -- until victory," footage posted online by his office showed him saying, on his first such trip since the war began October 7. "Nothing will stop us, and we are convinced that we have the power, the strength, the will and the determination to achieve all the war's goals, and we will."
A source close to Hamas said Sunday the Islamist movement was willing to extend the current truce with Israel in Gaza for two to four days beyond its initial expiry Monday.
"Hamas informed the mediators that the resistance movements were willing to extend the current truce by two to four days. The resistance believes it is possible to ensure the release of 20 to 40 Israeli prisoners," the source told AFP, referring to hostages seized in the October 7 attacks.
Earlier today, Qatar's Ministry of Foreign Affairs spokesman said that a total of 39 Palestinians held by Israel are to be released from prison on Sunday.
As part of agreed commitments, on the third day of the Gaza truce, "39 Palestinian civilians will be released today in exchange for the release of 13 Israeli detainees from Gaza, in addition to a detainee holding Russian citizenship and 3 Thais," Majed Al-Ansari said in post on X, formerly Twitter.
According to the details, Hamas fighters released a third group of hostages including a four-year-old American girl on Sunday with more Palestinian prisoners set to be freed in exchange, as a source close to the group said it was willing to prolong a truce.
The exchanges under a four-day ceasefire that started Friday have been the first relief for captives' families since the fighter group attacked Israel on October 7, prompting devastating Israeli bombardments of the Gaza Strip.
The Israeli army said Sunday that 13 released hostages were back on Israeli territory, and another four were on their way to Egypt.
United States President Joe Biden announced that the 13 released included a four-year old American girl.
"She's been through a terrible trauma," Biden said of the girl, Abigail, whose parents were murdered by Hamas fighters in the unprecedented attacks.
The other four were released outside the terms of the truce -- including one Russian-Israeli who Hamas said was freed "in response to the efforts of Russian President Vladimir Putin".
Those freed were among around 240 captured on October 7 when Hamas fighters broke through Gaza's militarised border with Israel to launch the deadliest attack in Israel's history, killing about 1,200 Israelis and foreigners, according to Israeli authorities.
In response, Israel launched an air, artillery and naval bombardment alongside a ground offensive to destroy Hamas, killing nearly 15,000 people, mostly civilians and including thousands of children, according to the Hamas government in Gaza.
Sunday's releases bring the total number of Israelis freed under the deal to 39 since Friday.
In exchange, a further 39 Palestinian prisoners were freed on Sunday, the Israeli prison service said.
This followed the release of 78 other Palestinian prisoners from Israeli jails over the past two days.
A source close to Hamas said the Islamist movement, which has an armed wing, was willing to extend the current truce for up to four days beyond its initial expiry date.
"Hamas informed the mediators that the resistance movements were willing to extend the current truce by two to four days," the source told AFP.
"The resistance believes it is possible to ensure the release of 20 to 40 Israeli prisoners" in that time, they added.
Under the truce, 50 of the hostages held by the militants are to be freed over four days in exchange for 150 Palestinian prisoners, with a built-in extension mechanism to prolong the process as long as at least 10 Israeli captives are released each day.
A Qatari operations team visited Israel to "coordinate with the parties on the ground and with counterparts in Doha to ensure the deal continues to move smoothly, and to discuss further details of the ongoing deal", according to a source with knowledge of the talks.
Biden said Sunday he hoped the truce brokered by Egypt, Qatar and the United States, would extend "beyond tomorrow".
Israeli leaders have tempered hopes of a lasting halt to the offensive.
Prime Minister Benjamin Netanyahu said on Sunday: "We continue until the end -- until victory."
Dressed in green military fatigues and surrounded by soldiers, he vowed to free all the hostages and "eliminate Hamas", in footage posted online by his office.
He spoke while making the first visit to Gaza by an Israeli prime minister since 2005.
"Nothing will stop us, and we are convinced that we have the power, the strength, the will and the determination to achieve all the war's goals, and we will."
In the southern Gaza town of Khan Yunis, residents received a text message from Israeli forces that said: "We know there are hostages being held in Khan Yunis. The army will neutralise anyone who has kidnapped hostages."
Elswhere in Gaza, residents ventured back to pick through the ruins of their homes among heaps of rubble following weeks of bombardments.
"I came to see if there was anything left, if there was anything I could salvage. We fled with nothing," said Oussama al Bass, inspecting the ruins of his home in Al-Zahra, south of Gaza City.
"It's nothingness, everything is destroyed, everything is lost," he said. "We're tired. That's enough. We can't take it anymore."
On the outskirts of Gaza city, families took to the road on foot to head south, pushing luggage and relatives in wheelchairs, and carrying children in their arms.
Hamas's military wing, the Ezzedine al-Qassam Brigades, said Sunday that its northern brigade commander Ahmed Al-Ghandour and four other senior leaders had been killed, without specifying when.
In the previous round of captive releases, relatives voiced joy at the return of hostages including a nine-year-old Israeli-Irish girl, and cheering crowds greeted Palestinian prisoners as they left a jail in the West Bank.
"We are overjoyed to embrace Emily again, but at the same time, we remember... all the hundreds of hostages who have yet to return," her family said.
Among the group of Palestinians released earlier was 38-year-old Israa Jaabis, sentenced to 11 years in jail for detonating a gas cylinder at a checkpoint in 2015.
"I... have pain on an emotional level and I am missing my relatives. But this is the tax a prisoner pays," she said after returning to her home.
Saturday's releases went ahead despite a last-minute delay that highlighted the fragile nature of the process.
Hamas had accused Israel of breaking the terms of the agreement. Israel denied the allegation.
The pause in fighting has allowed more aid to reach Palestinians struggling to survive with shortages of water and other essentials.
Adnan Abu Hasna, a spokesman for the UN agency for Palestinian refugees (UNRWA), warned of "unprecedented" humanitarian needs.
"We should send 200 lorries a day continuously for at least two months," he said.
Gaza civil defence spokesman Mahmoud Bassel called for deliveries of heavy machinery "to search for survivors and bodies and to clear the ruins."
The UN estimates that 1.7 million of Gaza's 2.4 million people have been displaced by the fighting.
