Turkey scrambled two F-16 fighter jets after a SU-24 aircraft belonging to the Syrian army came closer to the border, the Turkey’s General Staff has said in a statement, according to Hurriyet Daily News.

The Syrian warplane changed its route when it was 3.6 sea miles away from the border with Turkey, the General Staff said.

Air dogfights between the two countries have increased since a Turkish F-4 jet that was flying over the Mediterranean Sea was downed by Syria on June 22, 2012, causing an international uproar.

More recently, Turkey shot down a Syrian helicopter on Sept 16 after arguing that it had violated Turkish airspace by two kilometers.
