Russian forces conducted a drill in the Baltic Sea, including training to repel an underwater attack, the Defense Ministry said on Friday, as quoted by "Reuters".
The ministry said that units of divers "demonstrated skills in detecting and capturing a group of underwater saboteurs, as well as in using FPV drones to destroy unmanned boats of a hypothetical enemy".
The exercises were aimed in part at evaluating the navy's anti-submarine sabotage defense units, the statement said.
This is the second time in a month that Russia has held naval exercises with an anti-submarine component, after US President Donald Trump said on August 1 that he had ordered two US nuclear submarines to take up positions closer to Russia.
In the first week of August, the Russian and Chinese navies practiced pursuing and destroying an enemy submarine in the Sea of Japan.
The Defense Ministry released a video of the Russian Navy commander, Admiral Alexander Moiseyev, inspecting the exercise in the Baltic Sea, which included training to defend an airfield from attacks by enemy drones.
