Mediators announced a ceasefire deal between Israel and Hamas, pausing the devastating 15-month war that has destroyed most of the Gaza Strip.

The deal will pause fighting for six weeks and open negotiations for an end to the war altogether. Over those six weeks, 33 hostages will be exchanged for hundreds of Palestinian prisoners. Displaced Palestinians will be able to return to what’s left of their homes, and humanitarian aid will flow freely.

Trump announced the deal in a post on Truth Social.

“WE HAVE A DEAL FOR THE HOSTAGES IN THE MIDDLE EAST. THEY WILL BE RELEASED SHORTLY. THANK YOU!” he said.

An Israeli official told the Associated Press that the details of the deal were still being ironed out. The Israeli Security Council will meet on Thursday to discuss it.

According to a draft viewed by the Wall Street Journal, Hamas accepted verbal guarantees from the U.S., Qatar, Egypt, and Turkey that Israel would continue negotiations for a permanent ceasefire.
