Egypt said Friday it has agreed to send U.N. humanitarian aid trucks through Israel’s main crossing into Gaza, but it remained unclear if they will be able to enter the territory as fighting raged in the southern city of Rafah amid Israel’s escalating offensive there.

Meanwhile, the bodies of three more hostages killed on Oct. 7 were recovered overnight from Gaza, Israel’s army said Friday. The CIA chief met in Paris with Israeli and Qatari officials, trying to revive negotiations for a cease-fire and a hostage release.

Egyptian intelligence quietly changed the terms of a ceasefire proposal that Israel had already signed off on earlier this month, ultimately scuttling a deal that could have released Israeli hostages and Palestinian prisoners, and set a pathway to temporarily end the fighting in Gaza, according to three people familiar with the discussions.

The ceasefire agreement that Hamas ended up announcing on May 6 was not what the Qataris or the Americans believed had been submitted to Hamas for a potential final review, the sources said.

Just a few weeks ago, Israel, under extraordinary international pressure to respond to warnings of imminent famine in the Gaza Strip, announced new steps to increase humanitarian aid.

But after an Israeli military incursion into the southern city of Rafah this week, the flow of aid has come to a near-total stop, first closed off by Israel and then further restricted, officials say, by Egypt.

Aid officials warned that essentials like food and medicine were running dangerously low, threatening to worsen an already dire humanitarian crisis.

Israeli tanks rolled into the southern Gaza Strip early Tuesday, capturing the Palestinian side of the Rafah Crossing on the Egypt border, in what the military called a “pinpoint operation” against the Hamas terror group.

The ground incursion in the eastern part of the city of Rafah came after Jerusalem said a truce offer from Hamas the previous day did not meet its demands, and announced that it had okayed moving ahead with the long-threatened offensive.

Israel said the terms of a ceasefire proposal Hamas accepted on Monday remained “far from” meeting its demands and warned its military operations in Rafah would continue, even as it sent negotiators to talk to mediators.

In a statement Monday, Hamas said the head of its political bureau, Ismail Haniyeh, told the Qatari prime minister and Egyptian intelligence minister that the militant group had accepted their proposals for a ceasefire and hostage deal.

Hamas said it has accepted a ceasefire deal proposed by Egypt and Qatar which seeks to halt the seven-month war with Israel in Gaza.

In a statement Monday, Hamas said the head of its political bureau, Ismail Haniyeh, told the Qatari prime minister and Egyptian intelligence minister that the militant group had accepted their proposal.

The Israeli government is now reviewing the Hamas response, CNN has learned. The Israeli prime minister’s office has declined to comment at this stage.

Israeli officials said the cease-fire deal Hamas claims to have accepted from Egypt and Qatar on Monday was not approved by the Jewish state — and that it could be a “deception” by the terrorist organization. 

The stakes could hardly be higher at this moment. Israel is preparing to launch an offensive in Rafah, the last stronghold for Hamas — and a city where more than 1 million Palestinians have taken refuge while fleeing war elsewhere in the Gaza Strip.
