CAIRO — A US-born radical Yemeni cleric called for the killing of Americans in a new video message posted on radical web sites Monday.
Anwar al-Awlaki said Americans are from the "party of devils" and so don't require any special religious permission to kill.
In the 23-minute Arabic language message entitled "Make it known and clear to mankind," al-Awlaki said it was "either them or us." He also called all Arab and Yemeni leaders "corrupt" and said it was time for religious scholars to take charge.
US investigators say al-Awlaki's sermons have been a key inspiration for a string of militants, including possibly the Pakistani man who tried to detonate a car bomb in Times Square this year.
On Friday, al-Qaida in the Arabian Peninsula claimed responsibility for sending bombs through the mail in packages addressed to the US which was thwarted a week ago.
