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.

Hamas says it is consulting other Palestinian groups before giving a formal response to the latest proposal for a new Gaza ceasefire and hostage release deal put forward by the US. President Donald Trump said on Friday morning that expected to know within 24 hours whether Hamas has agreed to the plan.

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.
