MOSCOW, August 1. /TASS/. The Kiev regime made an unsuccessful attempt to attack Russian civilian vessels in the Black Sea by seaborne drones that were timely detected and destroyed by Russian naval ships, Defense Ministry Spokesman Lieutenant-General Igor Konashenkov reported on Tuesday.

"Last night, the Kiev regime made an attempt of a terrorist attack with three semi-submersible drones on Russian civilian freight vessels sailing towards the Bosporus Strait in the southwestern part of the Black Sea," the spokesman said.

The Russian naval ships that escorted the freight vessels timely detected and destroyed all the seaborne drones, the general said.
