UN Security Council urged to impose no-fly zone against Libya

The United States said the call by the Arab League for a UN no-fly zone over Libya was an important step, but while US said it was preparing for all contingencies, it has remained cautious over endorsing direct military intervention.The speed of the government advance may overtake drawn-out diplomatic wrangling on whether or how to impose a no-fly zone.On the other hand, doctors and other medical staff marched through the streets of Benghazi, pleading with the international community to enforce a no-fly zone over Libya. Libyas flat desert terrain means the governments air supremacy and big advantage in tanks outweighs the rebels enthusiasm and light weaponry. Only towns and cities provide some cover for the insurgents and partially even the odds.
