Israel’s National Institute of Forensic Medicine has identified the remains of two more hostages returned from Gaza, as officials and families warned Hamas to hand over the bodies of those still held.

DEIR AL-BALAH, Gaza Strip (AP) — Israel and Hamas moved ahead on a key first step of the tenuous Gaza ceasefire agreement on Monday by freeing hostages and prisoners, raising hopes that the U.S.-brokered deal might lead to a permanent end to the two-year war that ravaged the Palestinian territory.

After Hamas handed over two dead Israeli hostages overnight, Israel returns 30 dead Palestinians - a ratio agreed in the first phase of the peace deal.

The Israeli military said it had received coffins believed to contain the remains of two more deceased hostages.

Closing the three-hour service where speakers ranged from Peretz’s grandmother to Israel’s president, Shelley Peretz said the fact that her son had finally crossed back into Israel — on the Jewish holiday of Simchat Torah, the same as on the day he was taken — made all the difference.

President Donald Trump arrived in Israel Monday morning, where he addressed the Knesset and attended a regional peace ceremony in Egypt with global leaders following the Israel-Hamas ceasefire. Hamas released 7 hostages shortly before Trump's arrival.

Israel will allow Gaza's Rafah border crossing with Egypt to open on Wednesday and increase the amount of humanitarian aid coming into the enclave, public broadcaster Kan reported, after Hamas handed over more bodies of deceased hostages.

Israel is growing frustrated by the speed in which Hamas is releasing the bodies of deceased hostages, which Israel says violates the ceasefire agreement
