BAGHDAD — Abu Mohammed is a policeman by day, patrolling the Shiite Muslim district of Sadr City. Come sundown, however, Abu Mohammed commands a platoon of Jaish al Mahdi, or the Mahdi Army, a Shiite militia associated with radical cleric Muqtada Sadr that is widely accused of sectarian killings.
Abu Mohammed is not alone in this double life. By his account and those of U.S. military and Iraqi sources, Mahdi militia members have infiltrated much of the country's security apparatus, including the army, where they reportedly intimidate and bribe troops and commanders to look the other way as militants execute their brutal sectarian "cleansing" agenda.
"There is a Mahdi Army member in every family and in every home across Iraq and the military is not exempt," said Abu Mohammed, leaning nonchalantly in a Sadr City alley, as children played in the street. "The army wouldn't go after the Mahdi Army because many elements in the army are Mahdi Army. Here in Sadr City for example, there is one company and 35 of them are Mahdi Army."
Abu Mohammed, who insisted on identifying himself only by his battle name, represents one of the challenges U.S. strategists face in Iraq. While U.S. forces search out militia fighters and try to build a nonsectarian police force and army, men such as Abu Mohammed are surreptitiously undoing their work.
In addition to infiltrating Baghdad army units in Shiite neighborhoods, the Mahdi Army has been able to bring political pressure on commanders, and on at least one occasion, to create its own army units packed with its fighters.
The Sadr movement has used Iraqi soldiers and national police officers to push deeper into predominantly Sunni Arab districts in west Baghdad, U.S. Army officers said. It also swayed the leadership of an Iraqi army battalion in the spring to mount strikes in Fadil, a Sunni district in east Baghdad, the U.S. officers said.
The nexus has included soldiers carrying out killings or turning a blind eye as Sadr fighters slip through checkpoints. In late March, in the early phase of the U.S. military buildup, a Mahdi fighter who gave his name as Abu Haidar bragged to The Times that Iraqi army officers had provided vehicles to his group to carry out executions. "We have a deal with the Iraqi army and police," he said.
