""The Iraqi forces will follow them with vigour because they are not popular in Iraq," said Ahmed Chalabi, the veteran Iraqi politician, in an interview with The Independent. "People haven't forgotten about the Iraqis who were killed by private security men in Nisour Square." Security personnel from Blackwater USA are accused of killing 17 Iraqi civilians, including a mother and child, when they opened fire in the square in west Baghdad on 16 September last year."
