JERUSALEM/UNITED NATIONS/ANKARA - Hamas is expected to release all 20 living hostages held in Gaza early Monday morning, Israeli government spokesperson Shosh Bedrosian said on Sunday.

Speaking at a press briefing, Bedrosian said an international task force would be established to help locate the remains of hostages who died in captivity and whose bodies Hamas has been unable to find.

The ceasefire between Israel and Hamas held for a third consecutive day on Sunday, as both sides prepared for the exchange of Israeli hostages and Palestinian detainees.

Bedrosian said Israel expects all 20 living hostages to be handed over to the International Committee of the Red Cross Monday morning, before being transferred to Israeli forces in Gaza. From there, they will be taken to a military base in Israel and later for medical checks in hospitals, where they will reunite with their families.

She said a convoy of ambulances will be on standby in case urgent medical assistance is needed, adding that the Israeli military and hospitals were ready to receive the hostages earlier if Hamas moves ahead of schedule.

Under an agreement reached in Egypt's Sharm el-Sheikh, Hamas is to release 20 living and 28 deceased hostages within 72 hours of the Israeli army's withdrawal to the "yellow line" in Gaza, the first of three withdrawal stages, by Monday at 12:00 pm local time.

Hamas has already indicated that it may not be able to locate all the bodies of deceased hostages by that deadline.

Earlier on Sunday, media reports suggested that Hamas had told mediators it was ready to release the living hostages as early as Sunday, ahead of the agreed deadline, if Israel freed at least two of seven high-profile Palestinian prisoners who were previously removed from the release list. There was no official Israeli response.

US President Donald Trump is expected to arrive in Israel on Monday morning for a brief visit. He is scheduled to address the Knesset, meet with Prime Minister Benjamin Netanyahu and families of the hostages, and then travel to Egypt to co-chair a summit on Gaza with Egyptian President Abdel Fattah el-Sisi, attended by around 20 world leaders.

The deal, part of the US-proposed 20-point plan aimed at ending the war that began on Oct 7, 2023, also includes the release of about 2,000 Palestinian detainees and increased humanitarian aid access to Gaza, which has been devastated by Israeli bombardments.

Israeli Defense Minister Israel Katz said on Sunday that after the hostages are back home, all the remaining Hamas tunnels in Gaza will be destroyed by the Israel Defense Forces and an "international mechanism to be established under US leadership and oversight."

The war was triggered by a Hamas-led assault on southern Israel that killed about 1,200 people and led to the kidnapping of around 250. Israel's subsequent military campaign in Gaza, including two years of airstrikes, shelling, and ground operations, has killed at least 67,806 people and injured 170,066 others, according to Gaza's health authorities, in addition to causing famine and destroying the vast majority of the enclave's infrastructure and buildings.  

Israel's military campaign 'not over'

Netanyahu said Sunday that the country's military campaign "is not over," on the eve of the planned release of all living Israeli hostages and hundreds of Palestinian detainees under the next stage of the newly implemented Gaza ceasefire with Hamas.

In a televised address, Netanyahu hailed the planned release of the 20 remaining living hostages as a "historic event."

"Wherever we fought, we won," he said. "But the campaign is not over yet," he added, without giving further details.

He said Israel still faces "very big security challenges" ahead. "Some of our enemies are trying to regroup," he warned, vowing to ensure Israel's security.

Earlier in the day, Israel's military chief Eyal Zamir said that the country had achieved a "victory over Hamas." In a broadcast statement, Zamir said the victory came through a combination of sustained military pressure and diplomatic efforts.

Zamir added that Israel remains "in the midst of a multi-front war." He said the military "will continue to act in order to shape a security reality that ensures the Gaza Strip no longer poses a threat to the State of Israel and its civilians. Through our operations, we are reshaping the Middle East and our security strategy for the years ahead."

UN: Humanitarian scale-up 

The UN humanitarian scale-up in the Gaza Strip is well underway, with cooking gas entering Gaza for the first time since March, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) said on Sunday.

More tents for displaced families, frozen meat, fresh fruit, flour and medicines crossed into Gaza throughout the day on Sunday, OCHA said in a press release.

The United Nations and its partners distributed hundreds of thousands of hot meals and bread bundles, both in the south and the north, the office said.

OCHA said it has secured Israeli approval for more aid to move forward, bringing the amount in its cleared pipeline to 190,000 metric tonnes, including food, shelter items, medicine and other supplies.

"This is just the beginning," the office said, adding that as part of its plan for the first 60 days of the ceasefire in Gaza, the United Nations and its partners will expand the scale and scope of its operations to deliver life-saving aid and services to virtually everyone across Gaza.

Speaking to reporters on Thursday, UN Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator Tom Fletcher said that in the first 60 days of the ceasefire, humanitarians aim to increase the pipeline of supplies to hundreds of trucks every day, with supplies of 170,000 metric tonnes -- food, medicine and other supplies -- in place.

He said the United Nations will scale up the provision of food across Gaza to reach 2.1 million people who need food aid and around 500,000 people who need nutrition; restore the health system, including reestablishing community-level disease surveillance; target 1.4 million people with water and sanitation services; carry out a massive scale-up in shelter provision; and reopen temporary learning spaces to provide activities for 700,000 school-aged children.

The ceasefire deal between Israel and Hamas entered into effect on Friday, following three days of intensive negotiations in Sharm el-Sheikh, Egypt, between the two sides mediated by Egypt, Qatar, Turkiye and the United States.

Gaza peace summit in Egypt

Turkish President Recep Tayyip Erdogan will attend a Gaza peace summit to be held in Egypt's Red Sea resort city of Sharm El-Sheikh on Monday, according to his office on Sunday.

"Our president is scheduled to address the summit and also hold consultations with the leaders of the participating countries," Burhanettin Duran, head of the Directorate of Communications at the Turkish presidency, said in a post on the social platform X.

The Sharm El-Sheikh summit will finalize an agreement between Israel and Hamas, aimed at ending the war in Gaza, the Egyptian presidency announced in a statement on Saturday.
