President Donald Trump has issued a stark ultimatum to Hamas regarding the remaining hostages in Gaza, setting a Saturday deadline that could potentially reshape the current Middle East ceasefire. Here’s what you need to know about this developing situation.

President Donald Trump says that a precarious ceasefire agreement between Israel and Hamas should be canceled if Hamas doesn’t release all the remaining hostages it is holding in Gaza by midday on Saturday — though he also acknowledged that such a decision would be up to Israel.

Trump expressed frustration with the condition of the last group of hostages freed by Hamas and by the announcement by the militant group that it would halt further releases.
