An Israeli security official said the transfer of aid into the territory is halted "until further notice," the first major test of the ceasefire.

Israeli fire killed three people near a ceasefire line in Gaza on Monday, medics said, with U.S. envoys expected in Israel to try to push forward the fragile truce that faced its gravest test so far over the weekend.

Detainees seek to return to their normal lives in Gaza after being freed from Israeli captivity, where some say they faced torture and beatings.

As Israel and Hamas implement the first phase of a Gaza peace plan, questions remain unanswered over what comes next.

Health officials in Gaza confirmed Israeli airstrikes had killed more than forty people. Israel accused Hamas of killing two Israeli soldiers near Rafah in southern Gaza. President Trump has sent a high level US team back to Israel to oversee the next phase of the truce.

Israel said it has received the bodies of two more hostages, leaving 16 in the enclave. Gaza officials said they received the bodies of 15 more Palestinians released by Israel, some of which they say showed signs of beatings and abuse.
