Photos and video taken by Reuters photographers at the scene showed blood splashed in several locations around the facility: smeared on a warehouse floor surrounded by stacks of aid, soaked into the side of a box of baby supplies and pooled on the ground outdoors. At the nearby Al-Najjar Hospital, where many of the injured were taken, U.N. workers grieved over the body of their dead colleague, who lay on a stretcher still wearing the organization’s signature blue jacket, photos taken by other news agencies showed.
WAFA, the Palestinian Authority’s official news agency, reported that at least four other people were killed in the strike alongside Mr. Abu Hasna and the UNRWA worker.
Philippe Lazzarini, the head of the agency, said in a statement that the “attack on one of the very few remaining UNRWA distribution centers in the Gaza Strip comes as food supplies are running out, hunger is widespread and, in some areas, turning into famine.”
At least 165 UNRWA staff members have been killed while working in Gaza since the start of the war, according to the agency. It also said that more than 400 people had been killed while sheltering at UNRWA facilities that had collectively been hit more than 150 times during the war.
Mr. Lazzarini said that UNRWA shared the coordinates of all of its facilities in Gaza on a daily basis with the “parties to the conflict,” and that the Israeli military had received the coordinates of the food distribution center on Tuesday, a day before it was hit.
“Attacks against U.N. facilities, convoys and personnel have become commonplace, in blatant disregard to international humanitarian law,” Mr. Lazzarini said.
Martin Griffiths, the top humanitarian chief at the United Nations, condemned the strike on the warehouse on social media, calling it “devastating” for both aid workers and “for the families they were trying to help.”
“They must be protected,” he said. “This war has to stop.”
