Teams from Egypt and the International Committee of the Red Cross (ICRC) have been allowed to search for bodies of deceased hostages taken during the 7 October attacks, Israeli authorities have confirmed.

The Israeli government said the teams have been permitted to search beyond the so-called “yellow line” in the area controlled by Israeli forces in Gaza.

Hamas has transferred 15 out of 28 deceased Israeli hostages under the first phase of a US-brokered ceasefire deal, which requires it to hand over all hostage bodies. The group said it is now coordinating with Egyptian authorities.

Donald Trump has warned Hamas to start return the bodies “quickly, or the other countries involved in this great peace will take action”.

An Israeli spokesperson said the Egyptian team has been permitted to work with the ICRC to locate the bodies, and would use excavator machines and trucks for the search beyond the “yellow line”.

The “yellow line” marks the boundary running along the north, south and east of Gaza that Israel withdrew to, as part of the first stage of the ceasefire deal.

Until now, Israel has not approved the entry of such teams.

Egypt, along with Qatar and Turkey, is a key signatory of the Trump-brokered Gaza peace plan, which was signed in the Egyptian resort of Sharm el-Sheikh earlier this month.

The news will be welcomed by relatives, desperate to give them a proper burial.

On Sunday, an Israeli government spokesperson said that Hamas knew where the bodies were.

“If Hamas made more of an effort, they would be able to retrieve the remains of our hostages,” the spokesperson said.

Trump posted on his Truth Social platform on Saturday that action would be taken if the bodies of the deceased hostages were not returned quickly.

“Some of the bodies are hard to reach, but others they can return now and, for some reason, they are not. Perhaps it has do with their disarming,” he said.

Trump added: “Let’s see what they do over the next 48 hours. I am watching this very closely.”

On Sunday, Israeli Prime Minister Benjamin Netanyahu said Israel would determine which foreign forces it would allow as part of a planned international force in Gaza to help secure the ceasefire under Trump’s plan.

“We are in control of our security, and we have also made it clear regarding international forces that Israel will determine which forces are unacceptable to us, and this is how we operate and will continue to operate,” he said speaking at the start of a cabinet meeting.

On Friday, US Secretary of State Marco Rubio said “a lot of countries” had offered to be part of the force – but added Israel would have to be comfortable with participants.

This appeared to be a reference to Turkey, amid reports Israel had vetoed the country’s involvement.

It remained unclear, however, how such a force could be deployed without an understanding with Hamas.

Israel launched a military campaign in Gaza in response to the 7 October 2023 attack, in which Hamas-led gunmen killed about 1,200 people and took 251 others as hostages.

At least 68,519 have been killed in Israeli attacks in Gaza since then, according to the territory’s Hamas-run health ministry.
