BRUSSELS—NATO’s European commander on Thursday ordered three warships to move immediately to the Aegean Sea to help end the deadly smuggling of migrants between Turkey and Greece.
Jens Stoltenberg, the NATO secretary-general, said the warships, now under German command, will conduct reconnaissance and surveillance to help end Europe’s gravest migrant crisis since World War II.
Ships from NATO Standing Maritime Group 2 “will start to move now” on orders from U.S. Air Force Gen. Philip Breedlove, NATO’s supreme commander in Europe, Stoltenberg said.
