U.S. troops in Iraq are holding a top leader of an Iranian
    special forces group believed to be supplying weapons to 
    insurgents who are targeting and killing U.S. forces in 
    Iraq, U.S. officials said Monday. 

    Brig. Gen. Mohsen Chirazi, said to be the third-ranking 
    officer in the Iranian Quds Force, was arrested in late 
    December during a raid at the home of a man connected to 
    the leader of the top Shiite party in Iraq with deep ties 
    to the Iranian government, Abdul Aziz al-Hakim, according 
    to U.S. officials.
