The European Union is concerned that people-smugglers could open a new sea route to Italy from Albania if land borders in the Balkans are sealed, EU officials said on Sunday. Two decades after the 80-km (50-mile) Adriatic crossing saw shiploads of Albanians fleeing post-communist chaos, EU and Balkan leaders meeting in Brussels to try and control refugee movements planned to agree tighter supervision of the overland route to Albania from Greece, where most migrants enter Europe. "There is a risk that the route to Albania and Italy may become the new route in winter," one senior EU official told Reuters.
