In a drill recorded on video, Russian air force’s Su-30 SM aircraft engaged a group target, a small missile boat earlier decommissioned by the Black Sea Fleet.

The pilots trained maneuvering against anti-aircraft weapons, using means of electronic warfare and jamming before bombing the boat.

As UNIAN reported earlier, Russian occupation forces continue to extract gas from the Black Sea deposits in the exclusive (maritime) economic zone of Ukraine, according to the State Border Guard Service.

The national oil and gas holding Naftogaz of Ukraine has lodged a lawsuit against Russia with the Permanent Court of Arbitration in The Hague (The Netherlands) demanding compensation of US$5 billion for damages the company suffered as a result of Russia's illegal seizure of its assets in Crimea, according to Naftogaz press service.
