The Italian government on Sunday welcomed Libya's decision to bar foreign vessels from a stretch of water off its coast, as both countries struggle with a migrant crisis that has engulfed Europe in recent years.

The comments from Italian Foreign Minister Angelino Alfano came as a second non-governmental organisation announced it was suspending operations in the area in response to the Libyan move.

The Libyan government "is ready to put in place a search and rescue zone in its waters, work with Europe and invest in its coastguards," Alfano told La Stampa daily on Sunday.

"This sends a signal that the balance is being restored in the Mediterranean."

Libya's navy last week ordered foreign vessels to stay out of a coastal "search and rescue zone" for migrants headed for Europe, saying the measure was aimed at non-governmental organisations it accuses of facilitating illegal migration.

Six years since a revolution that toppled longtime dictator Moamer Kadhafi, Libya has become a key departure point for migrants risking their lives to cross the Mediterranean to Europe.
