Earlier this week, a new video posted in the Al-Shammukh jihadist internet website was featuring wanted radical Yemeni-US cleric Awlaki who believed to be holed up in a tribal area of Shabwa province in the south of Yemen.
Experts in Al-Qaeda's affairs said that Al-Awlaki was a key leader of Al-Qaeda in the Arabian Peninsula (AQAP), placing him on the top list of terrorism supporters.
Al-Awlaki, 39, rose to importance last year after he was linked a US army major who shot dead 13 people in Fort Hood, Texas, and to a Nigerian student accused of trying to blow up a Northwest Airlines flight on December 25.
