The Justice Department has brought fresh charges against former Blackwater Worldwide security contractors over a deadly 2007 shooting on the streets of Baghdad.

    The grand jury indictment announced Thursday charges four men with voluntary manslaughter and other crimes.

    The case stems from the shooting deaths of 17 Iraqi civilians. Blackwater security contractors were guarding U.S. diplomats when they opened fire at an intersection. Their lawyers have said the insurgents ambushed the guards.

    A judge dismissed the charges in 2009, saying the Justice Department mishandled evidence.

    A federal appeals court reinstated the case.

    Prosecutors agreed to dismiss charges against a fifth defendant, while a sixth pleaded guilty. (Associated Press)
