The US military has said it is investigating a video that appears to show a group of marines urinating on dead Taliban fighters.

The Marine Corps said the actions portrayed in the clip, which was posted online but has not yet been verified, were not consistent with its values.

Footage shows four men in military fatigues appearing to urinate on three apparently lifeless men.

The Taliban has condemned the video, but said that it would not damage preliminary peace talks taking place between the US, the international community and the Taliban.

The BBC's Quentin Sommerville in Kabul said there were concerns about how the general public in Afghanistan would react to the footage.
