More than 80 Palestinians were killed across Gaza on Thursday, according to health officials, as Israel intensified its strikes across the strip.

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.

The U.S. President said Israel “agreed to the necessary conditions to finalize” a 60-day ceasefire, “during which time we will work with all parties to end the war.”
