An American citizen currently held in Kuwait is claiming he was subjected to a harsh FBI interrogation this week. Nineteen-year-old Gulet Mohamed says he has been tortured and sleep-deprived since trying to renew his visa at a Kuwaiti airport last month. Mohamed says he has been extensively questioned about a 2009 study trip to Yemen and a later visit with family members in Somalia. On Wednesday, Mohamed said FBI agents subjected him to threats and rejected his pleas for an attorney while pressing him to admit to ties with militant groups. Mohamed has been unable to return to the United States since being placed on a no-fly list.
