I've just seen the Al-Jazeera footage. Its truly shocking. There were about 6-7 US soldiers. They had been partly undressed. Most had shots to the head. One Iraqi guy in a blue shirt was grinning from ear to ear trying to move some of the dead to get a better camera shot of the wounds.
They was also some interviews with some very scared captives. One was a black lady who was close to tears.
Its the worst nightmare for the coalition forces.
