Israel launched a wave of airstrikes across the Gaza Strip early Tuesday, saying it was striking dozens of Hamas targets in its heaviest assault on the territory since a ceasefire took effect in January.
Hospitals reported more than 400 people killed, including women and children.
The surprise attack shattered a period of relative calm during the Muslim holy month of Ramadan and raised the prospect of a full return to fighting in a 17-month war that has killed tens of thousands of Palestinians and caused widespread destruction across Gaza.
