On Monday, Nasser Hospital - the largest in southern Gaza and one of the few still partially operating in the Strip - was hit twice by Israeli strikes. At least 20 people were reportedly killed, including journalists and medical staff. The attack has drawn international condemnation and the United Nations has stated that there must be justice. Israeli Prime Minister Benjamin Netanyahu called it a tragic mishap. On Tuesday, the Israeli military stated that the strike targeted a camera positioned by Hamas, without providing further evidence, and emphasized that an investigation into the strike's authorization is ongoing.
