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 said it is seeking an end to the war and the unrestricted entry of humanitarian aid as it is expected to announce a decision on a new U.S. ceasefire proposal to which U.S. President Donald Trump said Israel had agreed.

Israel is intensifying military operations in one of the last Hamas strongholds in Gaza, as the sides stake out positions before ceasefire negotiations proposed by US President Donald Trump.The escalation comes as Hamas weighs  a call by Trump to enter a 60—day ceasefire during which it would return half of the 50 hostages it still holds and pursue mediated talks with Israel to end the war.
