American citizens have been making their way to Somalia in order to join up with the group responsible for the bombing in Uganda that claimed 76 lives.

The Washington Times:

A number of Americans have traveled to Somalia to join up with al Shabab as well as al Qaeda, according to a senior U.S. administration official.

The official, in a background briefing with reporters on Tuesday evening, said this is something "we have watched very, very closely."

Al Shabab has claimed responsibility for the bombings in the Ugandan capital Kampala on Sunday that claimed the lives of 76 people, including one American.

The official said U.S. law enforcement is "very vigilant for any indication of individuals from Somalia coming here to the United States to engage in these types of extremist and terrorist activities."

The Obama administration has indications to prove al Shabab was responsible for the attacks in Uganda, but the U.S. had no forewarning of these attacks.

"Al Shabab was very much on our radar screen... but we didn't have any advance warning about that attack," the official said.

Al-Shabab appears to be altering its focus, going from a largely Somali-based group to joining al-Qaeda's call for global jihad. The fact that several Americans have been recruited might mean that in the future, we will face a growing threat from these terrorists who probably speak excellent English and can blend into the background of any American city.
