UN: Deadly fire on Gaza ambulances possible Israeli 'war crimes'

The death of 15 medics and humanitarian workers in Gaza after shots were fired at their ambulances raises further concerns of "war crimes by the Israeli army," the UN High Commissioner for Human Rights said on Thursday.

"I am appalled by the recent killings of 15 medical personnel and humanitarian aid workers, which raise further concerns over the commission of war crimes by the Israeli military," Volker Turk told the UN Security Council.

The bodies of 15 rescuers and humanitarian workers, including eight from the Palestinian Red Crescent and one from the UN, were found near Rafah in what the UN Office for the Coordination of Humanitarian Affairs (OCHA) called a "mass grave."

OCHA said Tuesday the first team was killed by Israeli forces on March 23, and that other emergency and aid teams were struck one after another for several hours as they searched for their missing colleagues.
