    Najibullah Zazi, an Afghan-born man who is a permanent U.S. resident and was living in Colorado, plotted a suicide bomb attack on the New York subway system. He received training from al Qaeda in the remote Waziristan region of Pakistan, which borders Afghanistan. He drove to New York in preparation for the attack but discarded bomb-making materials after learning he was under surveillance from a local imam.

    U.S. Major Nidal Malik Hasan, a Muslim born in the United States, is accused of killing 13 and wounding 32 during a shooting rampage at the U.S. Army installation in Fort Hood, Texas. U.S. authorities learned later he had been communicating with the Muslim cleric Anwar al-Awlaki, who is an American but left the country soon after the Sept. 11, 2001, attacks and has since encouraged attacks against his homeland. Al-Awlaki is believed to be hiding in Yemen. Hasan is facing trial in a military court.

Officials say he told them he had received the bomb and training from AQAP in Yemen.
