(AP) - The U.S. Army has begun questioning Sgt. Bowe Bergdahl about his disappearance in Afghanistan that led to five years in captivity by the Taliban, his attorney and an Army spokeswoman said Wednesday.

Bergdahl was questioned at Fort Sam Houston in San Antonio, where he has been staying since returning to the U.S., said his attorney, Eugene R. Fidell.
"Sgt. Bergdahl answered all questions put to him. The interview is proceeding. It has been a productive expenditure of time," Fidell said in a telephone interview during a break in the questioning. Fidell declined to comment on what specific questions Bergdahl was asked.
Lt. Col. Alayne Conway, an Army spokeswoman, said Bergdahl was advised of his rights under Article 31 of the Uniform Code of Military Justice. Article 31 pertains to individuals being informed of the nature of the accusation against them and says that they do not have to make any statement to investigators.
