A Russian combat jet intercepted and came dangerously close to a Polish plane conducting a patrol for the European Union's Frontex border protection agency, Polish border protection officials reported in Warsaw on May 7. The Let L-410 plane was patrolling in international airspace in the Romanian deployment region on May 5 when it was approached by a Russian Sukhoi Su-35, the Polish border protection agency said. It accused the Russian combat plane of conducting "aggressive and dangerous maneuvers."
