On the morning of Aug. 4, the residents of the Russian city of Novorossiysk woke to a 112-meter-long Navy ship being towed back to port after it was hit by a drone attack on the Black Sea overnight. While the Russian Defense Ministry claimed there were no casualties or damage, videos of the Olenegorskiy Gornyak listing to one side as tugs towed the ship away for repairs pointed to a different story. The attack was the result of a joint operation between the Security Service of Ukraine (SBU) and the Ukrainian Navy, according to unnamed sources in the SBU cited by CNN and several Ukrainian media publications.
