Western and Arab leaders met in Paris to agree how to enforce the UN resolution
A joint operation to enforce a UN-backed no-fly zone over Libya has begun - aimed at protecting Libyan civilians from government forces.
France, in diplomatic terms, has been one of the main promoters of UN Security Council resolution 1973 allowing the use of force. French aircraft were the first to operate over Libya ensuring, according to French President Nicolas Sarkozy, that Libyan government aircraft could not operate over Benghazi.
But the US and Britain have also been key players, with a barrage of cruise missiles being launched from US and British surface ships and submarines over the weekend.
While the US is overseeing the operation, it has said it expects to hand over control to a coalition headed by France, Britain or Nato in a matter of days.
Canada, Italy, Spain, Belgium and Qatar are also offering military support
