Israeli planes and tanks pounded areas across the Gaza Strip overnight and on Sunday, destroying several residential buildings, witnesses said, as traumatized Palestinians hoped a US plan to end the war would soon ease their suffering.
US President Donald Trump, who had called for an end to the bombing, said on Saturday on his Truth Social platform that Israel had agreed to an "initial withdrawal line" inside Gaza and that "when Hamas confirms, the Ceasefire will be IMMEDIATELY effective."
Israel escalated its offensive as Egypt prepares to host delegates from Hamas, Israel and the United States, and Qatar, to kick off talks over the implementation of the most advanced effort yet to halt the conflict.
Hamas had drawn a welcoming response from Trump on Friday by saying it accepted certain key parts of his 20-point peace proposal, including ending the war, Israel's withdrawal, and the release of Israeli hostages and Palestinian captives.
But the group left some issues up for further negotiation, as well as questions unanswered, such as whether it would be willing to disarm, a key demand from Israel to end the war.
"Progress would depend on whether Hamas would agree to the map, which shows the Israeli army would remain in control of most of the Gaza Strip," said a Palestinian official, close to the talks.
"Hamas may also ask for a strict timetable for the Israeli withdrawal from Gaza. The first phase of talks will determine how things are going to proceed," he told Reuters, asking not to be named.
In Gaza City, which Israel describes as one of Hamas' last bastions, Israeli forces continued attacks and warned residents who left against returning, saying it was a "dangerous combat zone."
On Sunday, witnesses said Israeli planes escalated attacks against targets across the city, Gaza's biggest urban center.
This followed a tense night in which drones dropped grenades on the rooftops of residential buildings and troops blew up explosive-laden vehicles, demolishing dozens of houses in two Gaza City neighborhoods, Sabra and Sheikh Radwan.
