The official, who spoke on condition of anonymity to discuss the case, told The Associated Press that Michael D. Furlong directed a defense contractor to gather information about the region that could be shared with military units.

After military officials suspected that he was using Defense Department money for an off-the-books spy operation, defense officials shut down that part of the contract, the official said.

The story was first reported by The New York Times in Monday's editions, quoting unnamed military and business sources as saying that Furlong, now a senior civilian employee at Lackland Air Force Base in San Antonio, Texas, hired subcontractors who had former US intelligence and special forces operatives on their payrolls. The newspaper said some of the information collected by the contractors was used to track down and attack militants.

“The story makes some serious allegations and raises numerous unanswered questions that warrant further review by the department,” Pentagon spokesman Bryan Whitman said Monday.

The military in mid-2008 put Furlong in charge of a program to use private companies to gather information about Afghanistan's political and tribal culture, the Times reported. Part of the original $22 million contract that Furlong was directing remains intact, the official told AP, because it provides the funding for nine workers involved in information-gathering, translation and similar work. Those workers are employed by International Media Ventures with offices in Florida, Texas and elsewhere.

Nine employees from International Media Ventures were hired by the US military to serve as information analysts and in other administrative jobs at the International Security Assistance Force headquarters operations center in Kabul, said Maj. Steven Cole, a spokesman for the international military coalition in Afghanistan.

“We are not aware of, nor responsible for, any other activities performed by this company or any of its subsidiaries,” Cole said.

Lackland Air Force Base referred questions on Furlong to the US Strategic Command, who assigned him to work on the base. The command had no immediate comment on Monday.

The Times reported that command spokeswoman Col. Kathleen Cook declined to make Furlong available for an interview. Furlong is a retired air force officer, the newspaper said.

Some US officials interviewed by the Times said they became troubled that Furlong seemed to be running an off-the-books spy operation. "While no legitimate intelligence operations got screwed up, it's generally a bad idea to have freelancers running around a war zone pretending to be James Bond," one US government official told the Times.

Contractor and author Robert Young Pelton told the paper that the US government hired him to gather information about Afghanistan, but Furlong improperly used his work. "We were providing information so they could better understand the situation in Afghanistan, and it was being used to kill people," Pelton was quoted as saying.

Some officials told the Times it was unclear whether Furlong's program resulted in militants' deaths, but others involved in the operation said it did.
