Moammar Gadhafi vowed to launch a final assault on the opposition's capital Benghazi and crush the rebellion as his forces advanced toward the city and warplanes bombed its airport Thursday. In the face of Gadhafi's increasingly powerful offensive, the United Nations was to vote on a mandate Washington seeks to strike his forces on land, sea and air.
After weeks of hesitancy over imposing a no-fly zone in Libya, the United States made a dramatic about-face, calling for even more expanded action, including strikes on Gadhafi's ground forces besieging rebel-held cities.
The U.N. Security Council scheduled a vote early Thursday evening on a resolution that would open the way for that, establishing a no-fly zone but also authorizing member states to take all necessary measures" to protect civilians from attacks by Gadhafi's forces.
The change reflected the past week's swift reversal of the realities on the ground, where once-confident rebels are now in danger of being crushed under an overpowering pro-Gadhafi force using rockets, artillery, tanks, warplanes. That force has advanced along the Mediterranean coast aiming to recapture the rebel-held eastern half of Libya.
Gadhafi troops encircled the city of Ajdabiya, the first in the path of their march, but also had some troops positioned beyond it toward Benghazi, Libya's second largest city and the headquarters of the opposition's leadership.
