An Australian navy helicopter carrying up to 11 people crashed on the earthquake-devastated Indonesian island of Nias Saturday, the defense department said. The navy Sea King helicopter crashed near the town of Gunung Sitoli on Nias, off the west coast of Sumatra in the afternoon, a defense statement said. The helicopter was from an Australian navy transport ship that arrived from Singapore Saturday after three months providing tsunami relief at the Indonesian province of Aceh. Up to 11 people, including the helicopter's crew of three, were on board, the statement said. No details of casualties were released.
