(CNN) – The two New Jersey men arrested at a New York airport Saturday planned to travel to Somalia to "wage violent jihad," authorities say. It's a specific case that reflects a bigger picture of the growing concern U.S. officials have about Somalia's role as a training ground for extremists.

CNN has learned the United States now estimates as many as 200 foreign fighters may be in Somalia – fighters posing a possible threat to the United States after joining the Somali-based al Qaeda group known as al Shabab. Our Pentagon correspondent Barbara Starr has the report.
