President Donald Trump said he expects to hear back from Hamas within 24 hours about the latest peace deal in Gaza brokered by the United States.

Hamas is seeking guarantees that a new U.S.-backed ceasefire proposal for Gaza would lead to the war's end, a source close to the militant group said on Thursday, as medics said Israeli strikes across the territory had killed scores more people.

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.
