By Alexander Cornwell and Nidal al-Mughrabi TEL AVIV/CAIRO (Reuters) -At least 20 Palestinians were killed on Friday in an Israeli airstrike in Gaza, according to local health officials, as U.S. President Donald Trump said he expected Hamas to respond to his "final proposal" for a ceasefire in Gaza in the next 24 hours.

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.”

U.S. President Donald Trump says Israel has agreed on terms for a new 60-day ceasefire with Hamas and that Washington would work with both sides during that time to try to end more than 20 months of war in Gaza.
