Commanders in Afghanistan  are bracing themselves for possible riots and public fury triggered by the publication of "trophy" photographs of US soldiers posing with the dead bodies of defenceless Afghan civilians they killed.

Senior officials at Nato's International Security Assistance Force in Kabul have compared the pictures published by the German news weekly Der Spiegel to the images of US soldiers abusing prisoners in Abu Ghraib in Iraq which sparked waves of anti-US protests around the world.

They fear that the pictures could be even more damaging as they show the aftermath of the deliberate murders of Afghan civilians by a rogue US Stryker tank unit that operated in the southern province of Kandahar last year.

Some of the activities of the self-styled "kill team" are already public, with 12 men currently on trial in Seattle for their role in the killing of three civilians.
