A branch of al Qaeda in Yemen is claiming responsibility for the attempted Christmas Day attack on a Northwest flight. The group said it was revenge for alleged U.S. strikes on Yemeni soil.
Right now among those being sheltered in Yemen is the Muslim cleric who corresponded with the suspect in the Fort Hood rampage and former Guantanamo Bay inmates who've joined Yemen's al Qaeda.
All this is raising concern that Yemen could be the next front in the war on terror.
On Tuesday's American Morning we discussed the development with Ian Bremmer, president of the Eurasia Group, and Fawaz Gerges, professor of Middle Eastern politics at the London School of Economics.
