The first phase, spanning a 42-day ceasefire, would see the exchange of 33 Israeli hostages in Gaza for Palestinians held in Israeli prisons, U.S. officials said.

Months of shuttle diplomacy have failed to end the war in Gaza, which began after Hamas launched a surprise attack on Israel on Oct. 7, 2023 that killed 1,200 people and saw 250 taken hostage. Around 105 captives were later released in a weeklong cease-fire in November 2023 in exchange for 240 Palestinian prisoners.

Negotiators in Qatar appeared close on Wednesday to sealing a deal for a ceasefire in the war in Gaza. Hamas had given verbal approval to the ceasefire and hostage return proposal under negotiation in Qatar and was waiting for more information to give final written approval, a Palestinian official, who asked not to be named, told Reuters.
