An Israeli airstrike on a UN-operated school in Gaza has killed at least 18 people, including six staff members of the United Nations Relief and Works Agency (UNRWA), and injured over 18 others. The strike targeted the al-Jaouni school in Nusseirat, which was being used as a shelter for approximately 12,000 displaced Palestinians. The Israeli Defense Forces (IDF) claimed the school was being used by Hamas as a command center, while UN officials and other sources condemned the attack as a violation of international humanitarian law. The UN Secretary-General António Guterres called for an immediate ceasefire and the unconditional release of all hostages. This incident marks the fifth time the school has been struck since the war began in October 2023, with the total death toll in Gaza exceeding 41,000. The situation continues to draw international condemnation and highlights the severe humanitarian crisis in the region.
