President Donald Trump has ramped up expectations around a possible 60-day ceasefire in the war in Gaza after he said Thursday that a response from Hamas was expected within the next day.

At least 15 Palestinians were killed overnight in an Israeli airstrike in Gaza, according to local health officials, as U.S. President Donald Trump said he expected Hamas to respond to his "final proposal" for a ceasefire in Gaza in the next 24 hours.

The rise of Izz al-Din al-Haddad in the chain of command suggests the group will hold firm to its position demanding a total end to the war before releasing all remaining hostages.
