Baghdad Iraq -

Baghdad --- Three neighborhood security guards were killed and two injured early Friday when U.S. attack helicopters fired at their checkpoint south of Baghdad, Iraqi police said. It was the latest in a series of complaints about errant strikes, which have stoked tensions between the citizen security groups in central and northern Iraq and their American backers.Mohammed Ghuriari, who heads the so called Awakening Councils that supply fighters to protect neighborhoods in the north of Babil province, said it was the third U.S. led strike on their checkpoints in less than two months. He said 19 people had been killed and 14 injured."the U.S. led forces should learn from their mistakes." Ghuriari said in a telephone interview, "such repeated attacks will make the Awakening Councils review their stance in the agreements they signed with the U.S. forces."
