Negotiations between Israel and Hamas hit a last-minute snag, delaying the expected announcement of a ceasefire agreement to pause the devastating 15-month war in the Gaza Strip.

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.

Negotiators said a deal between Israel and Hamas was closer than ever even as Israeli airstrikes on Gaza continued, killing at least 13.
