Crew members perform pre-flight preparations on Italian Tornado ECR fighters at the Trapani Birgi air base in the southern island of Sicily on March 18, 2011. Italy on March 18 offered the use of its air bases to impose a no-fly zone on Libya and said it could help take out Libyan radars and defence systems after the UN cleared the way for air strikes. Italy has 'granted the use of military bases on its national territory', the government's press office said after an emergency cabinet meeting in Rome.
