The Taliban have released video footage of a hostage, who they say is Bowe Bergdahl, a US soldier abducted near the Afghan-Pakistani border in June.

The man shown in the video identifies himself as the missing soldier and is wearing sunglasses and what appears to be a US military uniform. However, his identity has not yet been confirmed by other sources.

In the message, the man tells the people of the United States to call a halt to the war in Afghanistan and warns that otherwise it will turn into a second Vietnam.
