The U.N. envoy for Libya is calling for the European Union mount a naval blockade of Libya's coasts to help ensure security and prevent any violence from reaching Europe.

In an interview published Saturday with Italian daily Corriere della Sera, Bernardino Leon says he not only favors a blockade, but that it is necessary and the only thing that can be done concretely at this time.

Leon was quoted as saying he was certain that such a mission would receive the blessing of the U.N. Security Council.

Leon gave the interview from Rabat, Morocco, where he is presiding over the first round of talks between representatives of the two rival Libya parliaments on forming a national unity government.
