(ASSOCIATED PRESS) Palestinian militants carried out the deadliest single attack on Israel’s forces since the Hamas raid that triggered the war, killing 21 soldiers, the military said Tuesday, a significant setback that could add to mounting calls for a cease-fire. Hours later, the military announced that ground forces had encircled the southern city of Khan Younis, Gaza's second largest. That marked a major advance, but it was unclear how much closer it would bring Israel to defeating Hamas or freeing Israeli hostages — two central war aims that have proved increasingly elusive — as cease-fire talks appear to be gathering pace. Prime Minister Benjamin Netanyahu mourned the soldiers, who died when the blast from a rocket-propelled grenade triggered explosives they were laying. But he vowed to press ahead until “absolute victory,” even as Israelis are increasingly divided over whether it’s possible to both crush Hamas and free scores of captives. A senior Egyptian official said Israel has proposed a two-month cease-fire in which the hostages would be freed in exchange for the release of Palestinians imprisoned by Israel and top Hamas leaders in Gaza would be allowed to relocate to other countries. The official, who was not authorized to brief media and spoke on condition of anonymity, said Hamas rejected the proposal and is insisting that no more hostages will be released until Israel ends its offensive and withdraws from Gaza. Israel's government declined to comment on the talks. Egypt and Qatar — which have brokered past agreements between Israel and Hamas — were developing a multistage proposal to try to bridge the gaps, the official said. Families of the hostages have called for Israel to reach a deal with Hamas, saying time is running out to bring their relatives home alive. Israel launched its offensive after Hamas crossed the border Oct. 7, killing over 1,200 people and abducting some 250 others. More than 100 were released in November during a weeklong cease-fire. The offensive has caused widespread death and destruction, displaced an estimated 85% of Gaza's 2.3 million people and left one-quarter facing starvation. Iran-backed groups in Lebanon, Syria, Iraq and Yemen have meanwhile attacked U.S. and Israeli targets in support of the Palestinians. The U.S. and Britain launched another wave of strikes Monday against Yemen's Houthi rebels, who have targeted international shipping in the Red Sea. Lebanon's Hezbollah group said it fired rockets at a strategic military installation in northern Israel for a second time this month.
