Drone Strikes Turkish Tanker Carrying 1 Million Barrels of Russian Oil Near Istanbul

The M/T Altura, a Turkish-operated tanker carrying 140,000 tons of Russian crude oil, was struck by aerial and surface naval drones 15 nautical miles from the Bosphorus Strait early Thursday. The vessel, EU-sanctioned since October 2025 as part of Russia's shadow fleet, sustained damage to bridge and engine room. All 27 Turkish crew were unharmed. Turkey's transport minister confirmed the attack. No group claimed responsibility. The strike marks the closest such incident to a NATO member's major city and a critical international waterway.

Analysis
The M/T Altura attack 15 nautical miles from the Bosphorus is the closest such strike to a NATO member's major population center. Turkey has been threading a needle between NATO obligations and maintaining Russian energy trade; this strike forces a more direct reckoning. The use of both aerial and surface naval drones against a single target indicates an evolving multi-domain maritime strike capability. No attribution has been claimed.
