U.S. President Donald Trump on Sunday urged Hamas and Israeli negotiators gathering in Egypt for crucial talks aimed at ending the war in Gaza to "move fast," adding that there had been "very positive discussions" with the Palestinian armed group.

"There have been very positive discussions with Hamas, and Countries from all over the World (Arab, Muslim, and everyone else) this weekend, to release the Hostages, end the War in Gaza but, more importantly, finally have long sought PEACE in the Middle East," he posted on his Truth Social platform.

A senior Hamas official on Sunday said the Palestinian militant group is eager to reach an agreement to end the war and implement a prisoner swap with Israel, as negotiators converge in Egypt for talks.

Israeli Defense Minister Israel Katz said on Sunday that the military's offensive in Gaza City has so far displaced approximately 900,000 Palestinians.

Israeli and Hamas negotiators were converging on Cairo Sunday for talks to end nearly two years of war in Gaza, with Israel's leader expressing hope that hostages held in the devastated territory could be released within days.

Turkey said 36 of its citizens were expected to return home via a special flight on Saturday afternoon, after Israel intercepted a Gaza-bound aid flotilla.

Israel's army said Saturday that it would advance preparations for the first phase of U.S. President Donald Trump's plan to end the war in Gaza and return all the remaining hostages, after Hamas said it accepted parts of the deal while others still needed to be negotiated.

Hamas said Friday that it has accepted some elements of U.S. President Donald Trump's plan to end the war in the Gaza Strip, including giving up power and releasing all remaining hostages, but that others require further consultations among Palestinians.

The statement came hours after Trump said that Hamas must agree to the deal by Sunday evening, threatening an even greater military onslaught nearly two years into the war sparked by the Oct. 7 attack into Israel. There was no immediate response from the United States or Israel, which is largely shut down for the Jewish Sabbath.

U.S. President Donald Trump on Friday issued an ultimatum to Hamas of 2200 GMT Sunday to accept his Gaza peace deal or face "all hell."

The Palestinian militants have until "Sunday Evening at SIX (6) P.M., Washington, D.C. time," Trump posted on his Truth Social platform.

The organizers of a Gaza-bound aid flotilla said Israel intercepted its last remaining boat on Friday, after the interceptions of its fellow vessels drew protests worldwide.

The United Nations on Friday insisted there was no safe place for Palestinians ordered to leave Gaza City, and that Israel-designated zones in the south were "places of death".
