Russia¡¯s raid on a ship just off Turkey¡¯s coast brings the fallout from the Ukraine war to another NATO frontier and raises the stakes as Ankara seeks to coax Moscow back to a grain-export deal that would restore some calm to the Black Sea.

Armed marines raided the Turkish-based vessel via helicopter on Sunday some 60 kilometers off Turkey¡¯s northwest coast, in international waters but near Istanbul, in what Moscow called an inspection before it sailed on to Ukraine.

Turkey, NATO¡¯s second-largest military, has made no public comment on the incident that occurred far south of the war that has raged for a year-and-a-half in the north Black Sea.
