Israeli forces struck 800 targets across Gaza and killed hundreds of Hamas fighters, an Israeli military spokesperson said on Sunday.
Some militants were still inside Israel more than 24 hours after Saturday’s surprise assault, the spokesperson said. Dozens had been captured.
The death toll in Israel stood at 600 on Sunday evening. Health officials reported 370 deaths in Gaza.
Israel said its strikes inside Gaza targeted Hamas hideouts and military infrastructure.
At least three UN schools were damaged during the Israeli air raids, said the UN agency for Palestinian refugees, UNRWA. More than 20,000 people have sought shelter in UN schools around Gaza.
