Trump says 'good chance' of captive deal 'during the week'

US President Donald Trump said on Sunday there was a "good chance" of a hostage deal with Hamas "during the week", ahead of his upcoming meeting with Israel's Benjamin Netanyahu.

"I think there's a good chance we have a deal with Hamas...during the coming week," Trump told reporters amid mounting pressure on the Israeli prime minister to agree to a ceasefire and end the war on Gaza after almost two years.

Netanyahu said Sunday he hoped his talks in Washington could "help advance" a Gaza ceasefire deal.

Trump and Netanyahu are scheduled to meet at the White House on Monday, the Israeli prime minister's third visit since Trump returned to power in January.

Indirect negotiations between Israel and Hamas were underway in Qatar on Sunday, ending inconclusively, two Palestinian sources familiar with the matter said early on Monday, adding that the Israeli delegation didn't have a sufficient mandate to reach an agreement with Hamas.

"We've gotten a lot of the [captives] out, but pertaining to the remaining [captives], quite a few of them will be coming out," Trump added.

He said the United States was "working on a lot of things" with Israel, including "probably a permanent deal with Iran."

Trump also repeated claims that US strikes "obliterated" Iran's nuclear facilities during the 12-day Iran-Israel conflict.

Since the start of Israel's war on Gaza, mediators have brokered pauses in fighting during which hostages were freed in exchange for Palestinian prisoners held by Israel.

Of the 251 captives taken by Hamas members during the 7 October attacks, 49 are still being held in Gaza, including 27, the Israeli military says, are dead.

Israel's military campaign, lack of food and dire humanitarian conditions for more than 2 million people in the Gaza Strip have killed at least 57,418 people in Gaza, mostly civilians, according to the Gaza Health Ministry. The United Nations considers the figures reliable.
