The finding, according to reports, gave broad cover to covert U.S. forces in providing assistance to Libyan rebels. It comes amid an open debate by the Obama administration over whether to provide arms to the rebels, and a promise earlier during the U.S. Military intervention in Libya that no U.S. ground forces would be sent into Libya.

"I will reiterate what the President said yesterday – no decision has been made about providing arms to the opposition or to any group in Libya," Carney said. "We’re not ruling it out or ruling it in."

Some lawmakers have questioned the wisdom of arming the Libyan rebels, especially among some indications that some anti-Gadhafi forces might be allied with al-Qaeda.

Carney repeated what he told reporters during his daily press briefing, saying the U.S. is actively reviewing the possibility.

"We’re assessing and reviewing options for all types of assistance that we could provide to the Libyan people, and have consulted directly with the opposition and our international partners about these matters," he said.
