A rogue US army unit in Afghanistan killed civilians at whim and documented each death by snapping photos of the body or taking physical "trophies". Now the military is trying to stop the photos from ever being published.

From The Guardian:

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.
