REUTERS - U.S. intelligence agencies knew that a U.S. Army psychiatrist who killed 13 people in Texas last week had been in contact with Yemen-based U.S. preacher Anwar al-Awlaki, who later praised him for the attacks.

* Awlaki served as an imam in California, and later in Washington, D.C. where he headed the Dar Al-Hijrah Islamic Center. He was also the Muslim chaplain at George Washington University, according to a website run by former UK Guantanamo inmates.
