The commander of U.S. Africa Command, Army Gen. Carter Ham, told reporters Wednesday that each of the three groups - al-Qaida in the Islamic Magreb, Somalia-based al-Shabaab, and Boko Haram - poses a "significant threat" not only in the areas in which they operate but also to the United States.
An even bigger concern, according to Ham, is that the three are looking for ways to work together more closely.
Ham also expressed worry that some of Libya's weaponry could fall into the hands of terrorists.
