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.

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.

Health officials at the Nasser Hospital in Khan Younis, southern Gaza, said the Israeli military had carried out an airstrike on a tent encampment west of the city around 2 a.m., killing 15 Palestinians displaced by nearly two years of war.
