WASHINGTON (AP) — Lawyers for a former Blackwater Worldwide security contractor charged in a deadly shooting in Baghdad are asking a judge to dismiss the indictment against him.

The lawyers representing Nicholas Slatten say a new indictment returned last month is barred by a 5-year statute of limitations. Slatten and three other Blackwater guards are charged with opening fire on Iraqis in a crowded Baghdad intersection in September 2007.
