An Iraqi extremist group whose main base was destroyed by U.S. and Kurdish forces last spring has emerged as the key terrorist threat to American forces in Iraq, a senior U.S. general said Thursday.

He would not say whether interrogations of Hawleri have provided any useful information. Full Story
