More Than 400 Killed As Israel Launches Airstrikes Across Gaza

Israel launched a wave of airstrikes across the Gaza Strip early Tuesday, saying it was hitting Hamas targets in its heaviest assault in the territory since a ceasefire took effect in January. The strikes killed more than 400 people and wounded over 500, according to Gaza's Health Ministry. Prime Minister Benjamin Netanyahu said he ordered the strikes because of a lack of progress in talks to extend the ceasefire. Officials said the operation was open-ended and was expected to expand. The White House said it had been consulted and voiced support for Israel’s actions. Hamas warned that Israel’s new airstrikes breached their ceasefire and put the fate of hostages in jeopardy.
