The U.S. Navy says an American-flagged cargo vessel has escaped a brush with armed pirates off the coast of East Africa. A spokesman for the U.S. 5th Fleet in Bahrain says the MV Harriette came under small arms fire from suspected pirates Monday aboard two skiffs about 360 nautical miles off Mombasa, Kenya. Lt. Nate Christensen says pirates came within three feet (a meter) of the vessel, but were unable to board. He says no one on the U.S. ship was injured. Christensen had not other details of the incident. The European Union"s anti-piracy force says a Norwegian warship clashed with suspected Somali pirates on Sunday, the Associated Press reported.
