Video shows U.S. Soldier Bowe Bergdahl alive after more than 4 years of captivity under the Taliban.

The U.S. military has acquired a video showing Sgt. Bowe Bergdhal, an American prisoner of war, alive after more than four years of captivity. According to CNN, the proof of life video shows the soldier in poor health on footage taken Dec. 14, 2013.

The Taliban-aligned Haqqani terrorist network is believed to be responsible for Bergdahl's imprisonment and the 'proof of life video,' CNN reports.

Bergdahl was captured in Afghanistan in June 2009, when he purportedly stepped away from a U.S. military base, according to NBC News.

Though an attempt was made to trade Bergdahl in exchange for five senior Taliban officials held in Guantanamo Bay, the exchange proved unsuccessful, USA Today said.

In a statement released by the Idaho National Guard, Bergdahl's parents said that the discovery of the video was "very important" to them and would help in their "resolve to continue efforts to bring Bowe home as soon as possible."

"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," the statement continued.

Other videos have been released of Bergdahl, but the last one was received more than three years ago, NBC News reported.

The video has also reinvigorated military efforts to bring the soldier home to his family.

"Sgt. Bowe Bergdahl has been gone far too long, and we continue to call for and work toward his safe and immediate release," a Pentagon spokesman told CNN.

"We cannot discuss all the details of our efforts, but there should be no doubt that on a daily basis –using our military, intelligence and diplomatic tools –we work to see Sgt. Bergdahl returned home safely," the spokesman said.
