Nairobi: Two officials have told The Associated Press that a UN helicopter trying to evacuate peacekeepers and civilians was fired on and sustained significant damage on Friday in the same restive South Sudan state where a US helicopter was hit on Saturday.

Rob McKee of Warrior Security said the UN helicopter was hit by small arms fire and made an emergency landing while trying to evacuate personnel from a base in Yuai in Jonglei state.

A second official who insisted on anonymity because the information hasn’t been released said the helicopter was abandoned and remains unable to fly. No injuries were reported.

A UN spokesman didn’t answer a phone call or email seeking comment.

US aircraft were fired on Saturday in Bor, the capital of Jonglei. Four US service members were wounded.
