Drone Attacks Sink Cargo Ship Off Bulgaria, 11 Missing

· Shipping · Bulgaria · Russia

Eleven sailors are missing after a drone attack sank a cargo ship off Bulgaria's Black Sea coast on Tuesday, possibly the second fatal sinking of a vessel in the area within a week. Bulgaria summoned Russia's ambassador over the incident, pointing to Moscow as drones struck two ships in the area near NATO waters. The attacks have heightened concern about the security of shipping in the Black Sea, a key corridor for grain and energy exports, as the war's spillover into commercial maritime traffic escalates. The immediate effect is renewed risk assessments for operators transiting the region and likely upward pressure on war-risk insurance premiums.

Why it matters：Attacks on commercial vessels near NATO waters raise war-risk premiums and force operators to reroute, deepening the security-driven fragmentation of Black Sea shipping.
