Efforts to stem the tide of migrants seeking the shores of Europe are working, NATO Secretary-General Jens Stoltenberg said Thursday, according to AP. Speaking at a news conference with Turkish Foreign Affairs Minister Mevlut Cavusoglu in Ankara, the Turkish capital, Stoltenberg said the collective effort is "making a difference" and that the number of migrants crossing the Aegean Sea is "going significantly down." Under an EU-Turkey deal signed last month, migrants arriving on Greek islands from the Turkish coast from March 20 onward face deportation to Turkey unless they successfully apply for asylum in Greece. The International Organization for Migration says Greece has seen fewer than 70 arrivals per day in the past 10 days, down from nearly 1,500 of arrivals per day before the deal was struck. Stoltenberg also visited NATO's flagship Bonn, which is part of a flotilla that began patrolling the Aegean Sea in February, and met Turkish President Recep Tayyip Erdogan.
