ANKARA — Two Turkish F-16 fighter jets followed a Russian reconnaissance plane that was flying parallel to the Turkish coast in international airspace. The General Staff said on its website Tuesday that an IL-20 type reconnaissance jet had flown near Turkey's Black Sea coastline and the Turkish Air Force responded by sending two F-16 fighter jets to intercept it. In other action, two F-16s were scrambled and directed toward the border region after a Syrian MI-8 helicopter approached Turkey's airspace. The Syrian aircraft left the area without violating Turkish airspace. Turkish F-16 jets were performing routine combat air patrol on the Turkey-Syria border over Hatay, a city on Turkey's southern border, which abuts Syria. Tensions in the area have remained high since Turkish forces shot down a Syrian warplane for entering its airspace on March 23.
