Turkish authorities said Monday that they had shot down a Syrian helicopter that violated the country's airspace, news reports said.
Deputy Prime Minister Bulent Arinc told reporters that Turkish fighter jets fired missiles at the helicopter after it flew slightly more than a mile into Turkey's Hatay province Monday afternoon, ignoring repeated warnings from air defense authorities.
