PARIS (AP) — A senior U.S. official says Sgt. Bowe Bergdahl  tells military officials that he was tortured, beaten and held in a cage

by his Taliban captors in Afghanistan after he tried to escape.

The official spoke on condition of anonymity because he's not authorized to discuss what Bergdahl is saying while being treated at a U.S. military medical facility in Germany.

The official says it is difficult to verify the accounts Bergdahl is providing about conditions of his captivity in the hands of the Taliban. He was released a week ago after nearly five years in captivity.

The New York Times reports Sunday that Bergdahl is not yet emotionally prepared to return to his family.

His release in exchange for five Taliban militants from Guantanamo Bay has ignited a political firestorm.

Meanwhile, threats against the Bergdahl's family are being investigated by federal, state and local authorities.

William Facer, a spokesman for the FBI's Salt Lake City division, said Saturday in a statement: "The FBI continues to monitor the situation in Hailey, Idaho. We are working jointly with our state and local partners and taking each threat seriously."  He did not detail the nature of the threat.

The soldier's parents, Bob and Jani Bergdahl, live in Hailey, Idaho.

On Wednesday, Bergdahl's hometown abruptly canceled plans Wednesday for a welcome-home celebration, citing security concerns over the prospect of big crowds -- both for and against the soldier.

The town of 8,000 has been swamped with hate mail and angry calls over Bergdahl, whose release after five years of Taliban captivity in Afghanistan has touched off a debate over whether the 28-year-old should be given a hero's welcome or punished as a deserter.
