GENEVA - The International Committee of the Red Cross (ICRC) said on Wednesday it had withdrawn its aid workers from Benghazi and called on both warring sides in Libya to spare civilians and medical staff. The independent humanitarian agency was among the only aid agencies deployed in the rebel stronghold in the east, where Libyan forces advanced on Wednesday as diplomatic steps to stop the bloodshed ran aground. "The International Committee of the Red Cross (ICRC) today (Wednesday) transferred its staff in Benghazi to the eastern city of Tobruk, where it will continue to assist victims of the conflict," the Geneva-based agency said in a statement.
