Qatari, Egyptian and US mediators called on Israel and Hamas Saturday to "finalise" the truce deal outlined by US President Joe Biden.
Fighting raged in the besieged Gaza Strip after US President Joe Biden said on Friday Israel was offering a new roadmap towards a full ceasefire.
Shortly after Biden's announcement, Israeli Prime Minister Benjamin Netanyahu insisted his country would pursue the war until it had achieved all its aims.
Hamas, meanwhile, said it "views positively" the Israeli plan laid out by Biden.
Several Palestinians were killed, and others were injured by Israeli strikes and shell cities in Gaza and Rafah early Sunday.
Israeli forces also demolished a Palestinian home in the occupied West Bank.
