A key energy facility on Russia’s Black Sea coast has come under repeated attack, as a marine terminal in Tuapse was hit by a drone strike for the fourth time in just two weeks.

The latest attack triggered a fire at the terminal after an unmanned aerial vehicle struck the site. Emergency crews were quickly deployed, working to contain the blaze and prevent it from spreading further, The Caspian Post reports via Ukrainian media.

Despite the scale of the incident, officials reported no casualties. A large-scale response operation was launched, involving 128 personnel and 41 units of equipment, including teams from the Russian Ministry of Emergency Situations.

The repeated strikes highlight growing pressure on critical infrastructure in Russia’s Black Sea region, raising fresh concerns over the vulnerability of energy and logistics hubs amid ongoing drone activity.

While the full extent of the damage remains unclear, authorities have launched an investigation.
