The North Atlantic Treaty Organization allies Friday agreed to speed up planning for possible military action in Libya , but the alliance has yet to decide whether to intervene in the conflict, a NATO official said.

The decision was made by ambassadors of the 28-nation alliance after the U.N. Security Council approved military action, including the enforcement of a no-fly zone, to stop Moammar Gadhafi's regime from defeating rebels.

"The ambassadors agreed to accelerate the military planning," a NATO official said on condition of anonymity, adding that envoys would meet again in the coming days to try to complete the process.
