The United Nations condemned the killing of three World Food Programme employees amid fighting in Sudan on Saturday, saying the three died while carrying out their duties, Reuters reports.

"I also am extremely appalled by reports of projectiles hitting UN and other humanitarian premises, as well as reports of looting of UN and other humanitarian premises in several locations in Darfur," Perthes, who is also the special envoy for the UN secretary general for Sudan, added in his statement.
