The Taliban have released video footage showing the moment they handed over US sergeant Bowe Bergdahl to American special forces in Afghanistan.

The video shows Bergdahl sitting in a pickup truck parked on a hillside in eastern Afghanistan's Khost province, as a dozen Taliban fighters with machine guns stand around the vehicle, one holding a white flag.

Wearing a traditional Afghan white tunic, the hostage sergeant is seen blinking frequently as he watches and listens to his captors.

Surveillance aircrafts fly overhead. Then a Black Hawk helicopter lands metres from the hillside where Bergdahl is now standing in front of the Toyota 4x4.

The 28-year-old is escorted half-way to the helicopter by his captors and is greeted by three Western-looking men in civilian clothing.

The three escort Bergdahl to the aircraft where soldiers in army uniforms are waiting.

A caption on the video posted on Islamist websites read: "Don't come back to Afghanistan!"

The sergeant had gone missing in unknown circumstances in Afghanistan in June 2009.

The Taliban released him last week in exchange for five Guantanamo Bay detainees.
