A sailboat carrying migrants sank in the Aegean sea between Turkey and Greece on Tuesday and at least 17 people were missing, Greek authorities said. Greece's maritime ministry said Greek and Turkish rescue efforts had saved 16 of the between 33 and 37 migrants believed to be on board when the boat went down between the Greek islands of Farmakonisi and Agathonisi. "The operation is ongoing," said a spokeswoman for Greece's maritime ministry.
