Gaza's civil defence agency reported that 21 people were killed and dozens injured in a series of Israeli air strikes on Saturday, intensifying tensions amid an already fragile ceasefire between Israel and Hamas. The strikes followed an incident in which the Israeli military claimed an armed individual crossed a boundary and fired at soldiers, prompting retaliatory attacks on what it described as terror targets. Witnesses described scenes of destruction, including a burned-out vehicle in Gaza City, as civilians attempted to recover food from the wreckage. Both Israel and Hamas have repeatedly accused each other of violating the ceasefire, with recent days seeing some of the deadliest incidents since the truce began. According to local health officials, hundreds of Palestinians have been killed since the ceasefire took effect, while the overall death toll from the conflict continues to rise.
