Iran: "IN" in Iraq?

This is a matter of grave concern:

On January 20th, a team of twelve men disguised as U.S. soldiers entered the Provincial Joint Coordination Center in Karbala, where U.S. soldiers conducted a meeting with local officials, and attacked and killed five soldiers, and wounded another three. The initial reports indicated the five were killed in the Karbala JCC, however the U.S. military has reported that four of those killed were actually removed from the center, handcuffed, and murdered.

The American Forces Information Service provides the details of the attack in Karbala. Based on the sophisticated nature of the raid, as well as the response, or cryptic non-responses, from multiple military and intelligence sources, this raid appears to have been directed and executed by the Qods Force branch of the Iranian Republican Guard Corps. My sources agreed this is far to sophisticated an operation for the Mahdi Army or Badr Corps, while al-Qaeda in Iraq would have a difficult time mounting such an operation in the Shia south. "The Karbala Government Center raid the other day was a little too professional for JAM [Jaish al-Mahdi, or the Mahdi Army]," according to a military source.

This raid required specific intelligence, in depth training for the agents to pass as American troops, resources to provide for weapons, vehicles, uniforms, identification, radios and other items needed to successfully carry out the mission. Hezbollah's Imad Mugniyah executed a similar attack against Israeli forces on the Lebanese border, which initiated the Hezbollah-Israeli war during the summer of 2006.

We noted earlier that the RoE in Iraq have been changed to allow US military to kill or capture Iranians discovered inside Iraq. Roggio notes the same, and speculates that the change in RoE may be a result of this intelligence.
