Another video has surfaced in the United States that shows the American soldier Bowe Bergdahl, who went missing in Afghanistan in 2009, alive but in declining health.

Bowe Bergdahl has remained the only US soldier to be held captive by enemy forces. The NBC news report stated that the video was in a thumb drive and was intercepted by the US last week, However, the report does not disclose how or where was the thumb drive found. The video footage that is being viewed as the proof of life of the US Army Sgt. Bowe Bergdahl shows a frail and shaky Bowe, who seems to in declining health, talking about the recent death of Nelson Mandela.

Taliban insurgents, who claimed to be responsible for holding the US soldier have asked in return for the release of five Taliban prisoners held in Guantanamo Bay. The US Military officials have not been able to reach on an agreement.

The US Military intelligence sources have maintained that Bowe is the prisoner of Haqqani network operating out of Pakistan. Though the White House had announced its willingness to release the five Taliban detainees in return of Bowe, the negotiation still remains clouded.

The captors of Bowe had released several videos of Bergdahl in captivity, but the last one was released more than three years ago. Bergdahl's parents, in a statement released by the Idaho National Guard, called on their son to keep up the hope. "Naturally, this is very important to us and our resolve to continue our efforts to bring Bowe home as soon as possible," it read.

"As we have done so many times over the past 4 and a half years, we request his captors to release him safely so that our only son can be reunited with his mother and father...BOWE - If you see this, continue to remain strong through patience. Your endurance will carry you to the finish line. Breathe!"

Bergdahl, who is from Idaho, was enlisted in the Army in 2008 and was assigned to the 25th Infantry Division in Fort Richardson, Alaska. In 2009, he was deployed as a machine gunner to a combat outpost in Pakita Province, Afghanistan, a militant hotbed. On June 30, 2009, Bergdahl was reported missing after not showing up for morning roll call. Initially, the US army believed that he had deserted his regiment.
