The plans were not enthusiastically received last week but as the pro-Gaddafi attacks continue against the uprising, the UN and NATO are warming up to the idea. Until Gaddafi's air force is shut down there's a high likelihood of daily attacks against protesters and a protracted civil war. Without an air force, Gaddafi's troops will have a much more difficult time going on the offensive against the protesters.
Barack Obama has stepped up pressure on Colonel Gaddafi, saying the US and Nato allies were considering a military response to violence in Libya, with the list of options including arming the rebels.
Obama's remarks came as Britain and France made progress in drafting a resolution at the UN calling for a no-fly zone triggered by specific conditions, rather than timelines. Downing Street is hopeful that a resolution with clear triggers such as the bombing of civilians would not be subject to a Russian veto at the security council.
The foreign secretary, William Hague, told the Commons a no-fly zone would have to be supported by north African countries and rebel leaders and would also need an appropriate legal basis.
