DEIR AL-BALAH, Gaza Strip (AP) — Israel struck and destroyed another high-rise building in Gaza City on Monday after warning residents to evacuate, part of an offensive aimed at taking over the largest Palestinian city. The military said it was targeting Hamas observation posts and bombs placed around the 12-story office building.

Over several days, Israel has destroyed multiple high-rise buildings in Gaza City, accusing Hamas of putting surveillance infrastructure in them. It has ordered people to flee ahead of its ground offensive into the city of some 1 million residents, which experts say is experiencing famine.

U.S. President Donald Trump said he was giving his “last warning” to Hamas regarding a possible ceasefire, as Arab officials described a new U.S. proposal for the immediate release of all the remaining hostages in exchange for 3,000 Palestinian prisoners and a temporary ceasefire. A senior Hamas official called it a “humiliating surrender document,” but the militant group said it would keep negotiating.

In Jerusalem, two Palestinian gunmen opened fire at a bus station, killing six people and wounding 12 in the worst such attack on Israelis in nearly a year. Tensions have soared across Israel and the occupied West Bank in the two years since Hamas’ Oct. 7 attack out of Gaza ignited the war.

Gaza’s Health Ministry said hospitals received the bodies of 65 people killed by Israeli fire over the past 24 hours, with another 320 people wounded.

Four soldiers killed in Gaza City attack

The Israeli military said four soldiers were killed in Gaza City on Monday when a group of militants threw an explosive device into a tank. Another soldier was wounded in an ensuing gunbattle, according to the military, which said two of the militants were shot.

Israel’s offensive has killed most of Hamas’ top leadership and vastly diminished its military capabilities. But the group still carries out sporadic guerrilla-style attacks. More than 450 Israeli troops have been killed in Gaza since the ground invasion began in 2023.

The loss of more soldiers could further undermine support for the war in Israel, where mass protests have been held in recent weeks demanding a ceasefire agreement with Hamas that would return the hostages.

‘Last warning’ proposal

The “last warning” proposal, presented by Trump’s Mideast envoy, Steve Witkoff, calls for a negotiated end of the war and the withdrawal of Israeli forces from Gaza once the hostages are released and a ceasefire is established, according to officials familiar with the talks.

The prisoner exchange would include hundreds of Palestinians serving life sentences, added the officials from Hamas, Islamic Jihad and Egypt, who all spoke on the condition of anonymity to discuss closed-door talks. Details of the proposal were first reported by Axios.

Israeli Foreign Minister Gideon Saar, speaking to reporters in Hungary, confirmed that Israel had accepted the latest U.S. proposal and expressed hope it would succeed.

Bassem Naim, a senior Hamas official, said the proposal seemed designed to be rejected because it calls for the release of all hostages on the first day, and for Hamas to disarm, and it conditions the withdrawal of Israeli forces on the establishment of a government in Gaza acceptable to Israel.

He said Hamas and allied groups seek an agreement that will “end the war, halt the genocide, and open the horizon for a political solution that achieves our legitimate national goals, but not by signing a humiliating surrender document.”

An Egyptian official said the new proposal, which Arab mediators received from the U.S., was broader than previous ones and would require negotiations over ending the war, the withdrawal of Israeli forces and Israel’s demand that Hamas disarm.

Dispute over war’s end has stymied ceasefire efforts

Hamas-led militants abducted 251 people in the Oct. 7 attack and killed some 1,200, mostly civilians. Forty-eight hostages are still inside Gaza, around 20 of them believed to be alive.

Israel’s retaliatory offensive has killed at least 64,522 Palestinians, according to Gaza’s Health Ministry, which does not say how many were civilians or combatants. It says around half of those killed were women and children. Large parts of major cities have been completely destroyed, and around 90% of the population of some 2 million Palestinians have been displaced.

Hamas has said it will only return the remaining hostages — its only bargaining chip — in exchange for Palestinian prisoners, a lasting ceasefire and a full Israeli withdrawal from Gaza. It says it is willing to hand over power to politically independent Palestinians.

Israeli Prime Minister Benjamin Netanyahu has rejected those terms, saying the war will continue until all the hostages are returned and Hamas has been disarmed. He says Israel will maintain open-ended security control over Gaza and facilitate what he describes as the voluntary emigration of much of its population, which the Palestinians and many others see as a plan for forcible expulsion.

Mediators had previously focused on brokering a temporary ceasefire and the release of some hostages, with the two sides then holding talks on a more permanent truce. Witkoff walked away from those talks in July, after which Hamas accepted a proposal that the mediators said was almost identical to an earlier one that Israel had approved.
