Even in a country beset by murder and death, the 16th Brigade represented a new frontier. The brigade, a 1,000-man force set up by Iraq's Ministry of Defense in early 2005, was charged with guarding a stretch of oil pipeline that ran through the southern Baghdad neighborhood of Dawra. Heavily armed and lightly supervised, some members of the largely Sunni brigade transformed themselves into a death squad, cooperating with insurgents and executing government collaborators, Iraqi officials say.
"They were killing innocent people, anyone who was affiliated with the government," said Hassan Thuwaini, the director of the Iraqi Oil Ministry's protection force. Forty-two members of the brigade were arrested in January, according to officials at the Ministry of the Interior and the police department in Dawra. Since then, Iraqi officials say, individual gunmen have confessed to carrying out dozens of assassinations, including the killing of their own commander, Col. Mohsin Najdi, when he threatened to turn them in.
Some of the men assigned to guard the oil pipeline, the officials say, appear to have maintained links to the major Iraqi insurgent groups. For months, American and Iraqi officials have been trying to track down death squads singling out Sunnis that operated inside the Shiite-led Interior Ministry. But the 16th Brigade was different. Unlike the others, the 16th Brigade was a Sunni outfit, accused of killing Shiites. And it was not, like the others, part of the Iraqi police or even the Interior Ministry. It was run by another Iraqi ministry altogether.
Such is the country that the new Iraqi leaders who took office Saturday are inheriting. The headlong, American-backed effort to arm tens of thousands of Iraqi soldiers and officers, coupled with a failure to curb a nearly equal number of militia gunmen, has created a galaxy of armed groups, each with its own loyalty and agenda, which are accelerating the country's slide into chaos.
