US troops kill 1 Iraqi, wound 3 in shooting at checkpoint

US troops killed one Iraqi and wounded three Monday north of Baghdad after opening fire at a vehicle they said failed to stop at a checkpoint after an operation targeting al-Qaida in Iraq, the military said. The shooting occurred after the American forces detained a man linked to senior leaders with the terror network who was allegedly involved in attacks in Tarmiyah, 50 kilometers north of Baghdad. The military said the US troops fired warning shots at a vehicle approaching their position as they were clearing the area, "but it continued to maneuver towards them at a high rate of speed." A second set of warning shots also was ignored, the military said.
