US authorities are investigating death threats sent to the parents of Bowe Bergdahl, the American soldier released by the Taliban last week after five years in captivity.
The FBI is examining four threatening emails sent to Bob Bergdahl and his wife Jani.
One of the emailed threats was sent to Bergdahl’s father on the day a rally in their hometown of Hailey, Idaho, celebrating his release was cancelled abruptly, amid controversy over the circumstances of his handover to US commandos in Afghanistan on 31 May.
Meanwhile, more detail has emerged about the harsh conditions of his captivity, according to anonymous sources. Bergdahl, 28, has told doctors that he was locked in a metal cage in darkness for weeks at a time and was tortured and beaten by his captors, according to US officials quoted anonymously by the Associated Press and the New York Times.
Bergdahl was held in a metal cage as punishment for trying to escape, the New York Times reported, and is now being treated in a medical facility in Germany for skin and gum disorders typical of poor hygiene.
