Somalis fleeing to Yemen prompt new worries in fight against al-Qaeda
...Yemeni officials, meanwhile, worry that al-Qaeda could lure Somali ex-fighters into their ranks with promises of money or aid. But so far, there has been no evidence of this, say Western diplomats and Yemeni officials.
In an audiotape last year, Osama bin Laden exhorted al-Shabab to overthrow the Somali government. Radical Yemeni American cleric Anwar al-Aulaqi, whom the United States has linked to the suspect in the attempted Christmas Day bombing and to the gunman charged in the massacre at Fort Hood, has also expressed support for al-Shabab.
