I believe this is because Gaddafi has threatened to attack any random civilian jet or ship in the med as it's a "ligitamate wastern target". To be honest though I wouldn't worry. His belief of what his military are capable are far in excess of what they actually are.
I don't think even Gaddafi is prepared to attack a state outside of his own.
Attack Malta/Southern Italy etc. and he's got a hell of a big problem on his hands - what is currently going is nothing in comparison.
Is the FR move indefinite or is there a time scale on it?
