Bihi, a spokesman for the family of 21-year-old Omar Farah, said Farah traveled to Somalia to join al-Shabab, renewing fears that the terror group is continuing to recruit U.S. Somalis to return to their homeland to fight despite some high-profile prosecutions in America and the deaths of some who have joined the insurgents.
