Washington (CNN) -- The U.S. military will no longer refuel its tankers at Manas air base in Kyrgyzstan, after the central Asian nation demanded to renegotiate its contract.
The military uses Manas to refuel its KC-135 airplanes, used for mid-air refueling of jets in Afghanistan. It has described the base as "hugely important."
Pentagon spokesman Bryan Whitman would not discuss the specifics of the negotiation but did offer one explanation.
"They are not proposing reducing the cost of fuel," he said.
Whitman said the military has other options for the KC-135 and the not using Manas would not affect U.S. air operations in Afghanistan. The United States will still use the Kyrgyz base to fly troops in and out of Afghanistan.
