On 16 September 2007 private security guards employed by the American firm Blackwater opened fire on civilians in Baghdad's Nisour Square. Seventeen Iraqis were killed, and another 20 injured. The Blackwater guards, who were escorting a convoy from the American embassy, claimed that they had come under attack from insurgents, but eye-witnesses and Iraqi offficials quickly dismissed that version of events. Mike Lanchin has been speaking to Mohammed Kinani who was driving through the area at the time, and whose 9-year-old son Ali, was shot dead by the Americans.
