A 2010 report by the Daily Mail quoted a Taliban captor of Bowe Bergdahl, the American soldier released in a deal announced this weekend in exchange for five Guantanamo Bay detainees, stating Bergdahl converted to Islam and was teaching Taliban fighters bomb-making skills.
The report came after about one year that Bergdahl had deserted his post in June 2009 while based in eastern Afghanistan.
At least six American soldiers reportedly lost their lives in attempts to return Bergdahl to his unit.
The captor, who called himself Haji Nadeem, said Bergdahl taught basic ambush training as well as how to take apart a cell phone and convert it into a remote control for a roadside bomb, he told the Sunday Times.
It has not been confirmed whether Bergdahl converted and if so, whether it was voluntarily or under the pressure of authorities to prevent getting killed.
