MINNEAPOLIS, Minnesota (CNN) -- Last month, 17-year-old Burhan Hassan told his family he was catching a ride to school with a friend. He then vanished.
His mother spoke to her son just a few days ago over the phone. To her shock, she says, he told her he was no longer in the United States.
"Mom, I'm in Somalia! Don't worry about me; I'm OK," the mother quoted her son as saying.
Details of how he got there and what has transpired in his life since his November disappearance are sketchy. His mother, who agreed to be identified only as Amina, says her son has clearly changed.
