Video posted on a pro-Taliban website shows footage of what is said to be a military dog "captured" during a battle between Taliban fighters and US forces.

The dog, wearing a vest with equipment is on a leash.

A narrator says the dog was captured along with weapons during a fight in which six Americans were killed.

The canine POW or prisoner of war's name is "Dagerwal," which means "colonel".

A Nato spokesman confirmed that a military working dog went missing during a mission in December, 2013. No other details were given.
