Israeli forces are investigating a strike in Gaza City that reportedly killed at least five people, including children, at a school-turned-shelter in the Tuffah neighborhood. The military stated that troops fired at suspects in structures outside their controlled area but did not clarify the threat posed. Gaza's civil defense agency, run by Hamas, said most victims were children and accused Israel of targeting civilians, though these claims could not be independently verified. The incident raises concerns about possible violations of the fragile ceasefire, with both sides accusing each other of breaches and international mediators working to maintain the agreement.
