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.

Israel confirmed that it agreed to a ceasefire proposal by President Donald Trump's Middle East envoy, Steve Witkoff, a day after Trump said the country had “agreed to the necessary conditions” for a ceasefire in the war in Gaza.
