The FBI says Mohamed is accused of providing material support to Al Shabaab, the Somali-based group that’s linked to al Qaeda. The group has launched many deadly terrorist attacks, including one on a popular mall in Kenya in 2013. The Westgate Mall attack lasted four days and killed dozens.
According to a FBI release Mohamed left the United States in the summer of 2012 attempting to join Al Shabaab. Interpol has sought him ever since.
