Israel has signed off on the latest U.S. ceasefire proposal for Gaza before it was sent to the Palestinian Hamas group, White House spokeswoman Karoline Leavitt said on Thursday.

President Donald Trump and special envoy Steve Witkoff submitted the proposal to Hamas after Israel signed off on it, she said.

"I can also confirm that those discussions are continuing, and we hope that a ceasefire in Gaza will take place so we can return all of the hostages home," Leavitt said at a briefing.

Asked if Hamas had accepted the proposal, she said, "Not to my knowledge."
