The articles, written by U.S. military "information operations" troops, are translated into Arabic and placed in Baghdad newspapers with the help of a defense contractor, according to U.S. military officials and documents obtained by the Los Angeles Times.

Many of the articles are presented in the Iraqi press as unbiased news accounts written and reported by independent journalists. The stories trumpet the work of U.S. and Iraqi troops, denounce insurgents and tout U.S.-led efforts to rebuild the country.

Though the articles are basically factual, they present only one side of events and omit information that might reflect poorly on the U.S. or Iraqi governments, officials said. Records and interviews indicate that the U.S. has paid Iraqi newspapers to run dozens of such articles, with headlines such as "Iraqis Insist on Living Despite Terrorism," since the effort began this year.

The operation is designed to mask any connection with the U.S. military. The Pentagon has a contract with a small Washington-based firm called Lincoln Group, which helps translate and place the stories. The Lincoln Group's Iraqi staff, or its subcontractors, sometimes pose as freelance reporters or advertising executives when they deliver the stories to Baghdad media outlets.
