Kenya's foreign minister told PBS Monday that two or three of the al-Shabaab terrorists who killed at least 68 people during an attack an siege at Nairobi mall last weekend were American teenagers.
The al-Qaida-affiliated terrorist group's recruitment of Somali teens in the United States and Canada is well documented. Federal prosecutors have charged and convicted dozens of people for providing material support to the group and other related crimes.
In this 2010 interview with the Investigative Project on Terrorism, Osman Ahmed explained why al-Shabaab's recruitment of young Somalis in America posed a wider threat than just Somalia. Ahmed's nephew was killed by Al-Shabaab terrorists after relatives complained about their relatives being solicited to join the group.
