Italy is warning that it will review the use of its bases by coalition forces for strikes against Libya if the mission doesn't pass to NATO's command.  Italian Foreign Minister Franco Frattini issued the ultimatum Monday after Turkey blocked NATO from approving a military strategy that would allow NATO's participation in the operation. Italy has allowed seven military bases to be used, and six Italian Tornados took part in operations over Libya on Sunday. (AP Photo/Luca Bruno)
