A US military helicopter made a "hard landing" Saturday after hitting wires in the northern Iraqi city of Mosul, killing two American soldiers, the US military said. The OH-58 Kiowa Warrior helicopter went down at about 6:10 p.m. in the eastern part of the city, the military said. "The incident appears to be combat-unrelated and there was no enemy contact in the area," it said. The helicopter hit a communications tower belonging to the main office in Mosul of the Patriotic Union of Kurdistan, a Kurdish political party, said a party official who requested anonymity because he is not authorized to speak to the media. The official said the accident cut electricity in the area.
