Akhir 13, 1432 H/March 18, 2011, SPA -- NATO envoys are considering ways to enforce a U.N. resolution authorizing the use of «all necessary measures» to protect civilians under attack by government forces in Libya, as AP reported. A diplomat said Friday that ambassadors are «meeting all the time» to review the situation. The U.N. Security Council on Thursday approved the resolution backed by the U.S., Britain and France. It effectively sets up a no-fly zone to prevent Col. Gadhafi's forces from mounting air strikes against anti-government rebels. Last week, NATO's defense ministers agreed that the alliance would act only with a clear legal mandate and strong regional support. Aircraft flying from NATO bases in Sigonella, Sicily, Aviano in northern Italy, and a U.S. carrier in the Mediterranean could enforce the no-fly zone.
