ISTANBUL (AP) — Turkish fighter jets shot down a Syrian warplane Sunday after it violated the country’s airspace, Turkey’s prime minister said, in a move likely to ramp up tensions between two countries already deeply at odds over Syria’s civil war.

A spokesman for Syria’s military confirmed the incident, denouncing it as a “blatant aggression.” The unnamed spokesman quoted on Syrian state TV said the plane was hit while pursuing gunmen near the border, and that the pilot safely ejected from the aircraft.
