NEW YORK, Sept. 29 (UPI) -- Two radical Islamic clerics with American roots have resurfaced amid an alert about a "credible" threat of commando-style terror attacks, officials say.
American-born Yemeni cleric Anwar al-Awlaki, linked to both the Fort Hood, Texas, shooting and the attempted Christmas Day bombing of Northwest flight 253, is expected to release new video, ABC News reported Wednesday.
Al-Qaida in the Arabian Peninsula, the Yemeni affiliate of al-Qaida, posted images from the forthcoming video on the Internet.
Authorities consider Awlaki an al-Qaida recruiter whose online videos inspire young Westerners to jihad and say AQAP is the most serious current threat to American cities.
Meanwhile, another "homegrown" radical, al-Qaida spokesman Adam Gadahn, has released a new Internet video about the Pakistan floods.
The videos come as U.S. and European authorities are searching for a team of commandos allegedly planning attacks in Britain, France and Germany.
U.S. law enforcement officials say they have been informed terrorists were planning "Mumbai-style" commando raids on "economic or soft" targets in those countries.
Pakistani militants killed 173 people with guns and grenades during the 2008 attacks in Mumbai, India.
