Six staff members of the United Nations killed in an Israeli airstrike in Gaza

United Nations Secretary-General António Guterres says what is happening in Gaza is unacceptable, and dramatic violations of international humanitarian law need to stop immediately. An Israeli airstrike on a central Gaza school being used as a shelter for displaced Palestinians killed 18 people. Among those killed were six staff members of the UN Palestinian refugee agency UNRWA. The school was sheltering around 12-thousand displaced people, mainly women and children.
