Israel carried out about 1,500 airstrikes against Hamas-linked targets in Gaza, while militants fired about as many rockets into Israel.
The Gaza-based Palestinian Center for Human Rights said that 156 Palestinians were killed, including 33 children and minors under 18. Rockets from Gaza killed six Israelis. The group says most of more than 1,000 wounded Gazans were civilians. Dozens of Israelis were also hurt.
Gaza's schools reopened on Saturday. Adnan Abu Hassna, spokesman for a U.N. aid agency, says tens of thousands of students at 245 U.N. run schools spent the first day talking about their experiences during the fighting.
