Bill Roggio surmises that the attack on American soldiers at Karbala in Iraq was carried out by Iranian commandos. If he's right then the new directive giving American troops the green light to kill or capture any Iranians found in Iraq makes even more sense:
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.
