Frontex suspended its Black Sea patrol operations after a Russian Su-35 jet dangerously intercepted a Polish Border Guard Service L410 TURBOLET aircraft conducting a routine patrol mission in international airspace.

On Friday, a Russian Su-35 jet dangerously intercepted Polish Border Guard Service's L410 TURBOLET aircraft, which was conducting a routine patrol mission in international airspace over the Black Sea under the auspices of Frontex and in cooperation with Romanian services.

A twin-engine Russian Su-35 fighter jet flew into the operational zone designated by Romania without any radio contact, after which it performed aggressive and dangerous maneuvers, closely approaching the Polish aircraft three times and violating safe separation standards.

The incident caused the Polish aircraft to experience severe turbulence. During the incident, the five members of the plane's crew temporarily lost control of the aircraft and began to lose altitude.

The Russian fighter jet also flew right in front of the border guards' plane, crossing its flight path at a dangerous distance, which the crew estimated to be about five metres.

Piotr Müller, spokesperson for the Polish government, has commented on the interception of the Polish border guard aircraft by a Russian fighter jet, saying it was a planned provocation.
