Iraqis give evidence in shooting trial

Three Iraqis, including the father of a dead nine-year-old boy, appeared before a US grand jury investigating the deadly shooting in Baghdad involving Blackwater Worldwide contractors.

The Iraqis were escorted to the closed-door session in Washington by prosecutors overseeing the US investigation into whether Blackwater security guards illegally fired into a crowded Baghdad junction on September 16 last year, resulting in the deaths of 17 Iraqi civilians.
