An Israeli airstrike hit the central Gaza Strip on Thursday, killing at least 25 Palestinians and wounding dozens more, Palestinian medics said, as U.S. President Joe Biden’s two top national security officials were in the region making a renewed push for an Israel-Hamas ceasefire.

Israel killed 13 Palestinians in two airstrikes on Thursday that Gaza medics and Hamas said were part of a force protecting humanitarian aid trucks, but Israel's military said they were Hamas militants trying to hijack the shipment.

Palestinian medics said Tuesday that Israeli airstrikes killed at least 25 people in the Gaza Strip. The medics said strikes hit a multi-story building in the Beit Hanoun area in northern Gaza, and that most of those killed were from the same family.
