Hamas is seeking guarantees that a new U.S. 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.

Trump said Tuesday that Israel had agreed on terms for a 60-day ceasefire in Gaza and urged Hamas to accept the deal before conditions worsen. The U.S. leader has been increasing pressure on the Israeli government and Hamas to broker a ceasefire and hostage agreement and bring about an end to the war.
