US official: Violence in Haiti hindering aid work

Some incidents of violence in Haiti have hindered rescue workers trying to help earthquake victims, a top official leading the US government's relief efforts said Sunday. Fear of looters has been one of the factors slowing aid delivery.

After Tuesday's earthquake, maintaining law and order fell to the 9,000 UN peacekeepers and international police already in Haiti even though those forces also sustained heavy losses in the disaster. Lt. Gen. Ken Keen of the US Southern Command said US forces are working with UN peacekeepers and that local police are beginning to assist in providing security.
