43 in Contractor’s Convoy Held After Baghdad Shooting
BAGHDAD — The Iraqi military detained 43 people in a convoy for a contractor with the United States military on Monday after the shooting of an 18-year-old woman in central Baghdad, the military said.

Witnesses and an Iraqi Army sergeant said a guard on the convoy wounded the teenager in the leg as she crossed the street in the bustling, mixed neighborhood of Karada.

While some early accounts said American security guards had been arrested, Maj. Brad Leighton, a spokesman for the military, said none of those arrested were Americans. The military said the episode involved Almco, a Dubai-based company under contract to the military.

Immediately after the shooting on Monday, a throng of angry civilians lashed out at the guard and beat him along with his passengers, believing they were insurgents, witnesses said.

The company has a construction contract with the Department of Defense's Joint Contracting Command Iraq and another contract to provide food, water and other basic services with the Multi-National Security Transition Command, which assists the Iraqi government with the development, organization and training of its armed forces.

The company does not handle any personal security for the American forces, but it is responsible for providing security for its own convoys, personnel and supplies while it is doing work related to its Department of Defense contracts.

Oh, and more horror, if you want it:

Elsewhere in Iraq, an apparent execution site filled with human remains and a torture chamber containing chains, heavy locks and shackles were found during a village raid in the province of Diyala, the American military reported. The military, which sent soldiers into the village earlier this month, said the sites belonged to the homegrown Sunni extremist group, Al Qaeda in Mesopotamia, which American intelligence believes is foreign-led. Eight insurgents were killed and 13 arrested during the raids, the military said, and a safe house containing false-identification materials was found.

The village, Abi Saida, is a known magnet for insurgent activity, and the military said it also found caches of arms there that included missiles, bombs and antiaircraft weaponry. The military said it had raided the suspect buildings in the village over a five-day period in early November and discovered the apparent execution site, where the remains of five people were found along with shell casings.
