Eight Iraqis were killed on Saturday, most of them security personnel, in a US air strike that apparently targeted their convoy by mistake west of Anbar, a provincial official said.  "Eight people -- a senior intelligence official, five policemen and a woman -- were killed by a US strike on the center of Al-Baghdadi," a town in western Iraq, the official said, asking not to be identified. "It seems the strike was a mistake," the official said of the incident in the Euphrates Valley town, adjacent to the Ain al-Asad airbase 250 kilometers west of the capital. The dead were traveling in a convoy which had been deployed to support an operation against suspected ISIS militants in the area. The strike destroyed most of the vehicles in the convoy and also wounded 20 people, including the towns police chief, who was in a serious condition, the provincial official said. Iraqs Joint Operations Command, which coordinates the campaign against ISIS, said it had ordered a special forces raid in the town after receiving intelligence of a "meeting to be attended by terrorist commander Karim al-Samarmad".  It said it had requested "air support from the international coalition". "Once the terrorist was arrested and while troops were carrying out searches, a grenade was thrown from an adjacent building." As the special forces troops returned to base, they ran into a convoy of police. The convoy was composed of pick-up trucks and the returning forces mistook them for militants and called in a coalition air strike, the JOC said. "An inquiry has been opened."
