Israeli airstrikes killed at least 46 people in the Gaza Strip in the past day, including 11 at a makeshift cafeteria in an Israeli-declared humanitarian zone, medics said.

The latest bombardment came as the United States said it would not reduce its military support for Israel after a deadline passed for allowing more humanitarian aid into Gaza. The State Department cited some progress, even as international aid groups said Israel had failed to meet the U.S. demands.
