Moawiya Hassanain, a Gaza Health Ministry official, said at least 145 people were killed and more than 310 wounded.
In the West Bank, Hamas’ rival, Abbas, said in a statement that he “condemns this aggression” and called for restraint, according to an aide, Nabil Abu Rdeneh. Abbas, who has ruled only the West Bank since Islamic Hamas militants seized power in Gaza last June, was in contact with Arab leaders, and his West Bank Cabinet convened an emergency session.
Israel has targeted Gaza in the past, but the number of simultaneous attacks was unprecedented.
Israel left Gaza in 2005 after a 38-year occupation, but the withdrawal did not lead to better relations with Palestinians in the territory as Israeli officials had hoped.
