CAIRO (AP) — U.S. President Donald Trump says Israel has agreed on terms for a new 60-day ceasefire with Hamas and that Washington would work with both sides during that time to try to end more than 20 months of war in Gaza.

Neither side has accepted the proposal announced Tuesday by Trump, who has admonished Hamas that if the militant group does not buy into the offer, its prospects will get worse. It’s not clear what conditions Israel agreed to.

The efforts to reach a truce are unfolding in the wake of powerful Israeli and American strikes on nuclear sites in Iran, which has long supported Hamas, and just days before Trump is scheduled to meet with Israeli Prime Minister Benjamin Netanyahu in Washington.

Here’s a look at the situation and the challenges it might present.

Details are murky

Details of the proposed ceasefire are just beginning to emerge. But rather than being completely new, the potential deal seems to be a somewhat modified version of a framework proposed earlier this year by Trump’s Middle East envoy, Steve Witkoff.

Trump said Tuesday in a social media post that Qatar and Egypt have been working on the details and would deliver a final proposal to Hamas.

An Egyptian official involved in the ceasefire talks told The Associated Press that the proposal calls for Hamas to release 10 more hostages during the two-month period — eight on the first day and two on the final day. During that period, Israel would withdraw troops from some parts of Gaza and allow badly needed aid into the territory.

The war began on Oct. 7, 2023, when Hamas-led militants attacked southern Israel, killing 1,200 people and taking roughly 250 hostages. The group is believed to still have some 50 hostages, with fewer than half of them thought to be alive.

The Egyptian official, speaking on condition of anonymity because he was not authorized to talk to reporters, said a sticking point over how aid would be distributed had been resolved with Israel.

He said both sides have agreed that the United Nations and the Palestinian Red Crescent would lead aid operations and that the Israeli- and U.S.-backed Gaza Humanitarian Fund would also continue to operate.

Hamas has been weakened

The unraveling of Iran’s regional network of proxies, capped by the blow inflicted on Iran during the recent 12-day war with Israel, has left Hamas weaker and more isolated in the region. Iran was a key backer of the militant group, but its influence has waned, and it’s now preoccupied with its own problems.

At the same time, Trump has made it clear to Israel that he wants to see the Israel-Hamas war end soon. While he has been supportive of Netanyahu, Trump had tough words for Israel in the opening hours of last week’s ceasefire with Iran, when he pressured Israel to scale back its response to an Iranian missile attack. That could help persuade Hamas to embrace a deal.

A diplomat briefed on the talks said there is now a “big opportunity” to reach an agreement. “The indications we’re getting are people are ready.”

He said Trump’s harsh talk toward Israel has “given a bit of confidence to Hamas” that the U.S. will guarantee any future deal and prevent a return to fighting. The diplomat spoke on condition of anonymity because he was discussing behind-the-scenes diplomatic contacts.

Israeli military positions and future talks pose obstacles

The Egyptian official said Israel has not yet agreed to a proposal to withdraw its forces to positions held in early March after a previous ceasefire officially expired. Since then, the Israeli army has seized large swaths of Gaza to put pressure on Hamas, and it’s not clear whether Israel is ready to return to those same positions.

An Israeli official characterized the agreement as a 60-day deal that would include a partial Israeli withdrawal from Gaza and a surge in humanitarian aid to the territory.

The mediators and the U.S. would provide assurances about talks on ending the war, but Israel is not committing to that as part of the latest proposal, said the official, who was not authorized to discuss the details of the deal with the media and spoke on condition of anonymity.

The Egyptian official said Hamas will have to review the proposal with other factions before submitting an official response.

One point that does seem to have been ironed out is the question of who will administer Gaza.

Israel has said Hamas cannot run the territory, and the Egyptian official said the proposal would instead put Gaza under a group of Palestinians without political affiliations known as the Community Support Committee once a ceasefire is reached.

Potentially complicating the effort, Netanyahu reiterated his hard-line position Wednesday, vowing that “there will be no Hamas” following the 60-day ceasefire plan.

Previous ceasefire did not last

A previous ceasefire agreed to in January established three phases, but the two sides never made it past phase one.

During that time, however, there were multiple exchanges of Hamas-held hostages for prisoners held by Israel, and critical humanitarian aid was able to reach Gaza.

When phase one expired on March 1, Israel sought to extend it while Hamas argued that phase two should go ahead as planned.

The second phase would have compelled Hamas to release all the remaining living hostages in exchange for more Palestinian prisoners, a lasting ceasefire and a full Israeli withdrawal from the Gaza Strip.

That was always seen as difficult, because it would have forced Israel to choose between its two main war goals — the safe return of the hostages and the annihilation of Hamas.

On March 18, Israel broke the ceasefire with new airstrikes and resumed hostilities.

In Gaza, residents expressed hope that this time, a ceasefire will bring an end to the war.

“We are seriously tired,” said Asmaa al-Gendy, who has been living in a tent camp in Deir al Balah with her two children. The family has been displaced and starved and endured “every form of torture in the world.”
