Drone strikes force Russia to shut Sea of Azov commodity route
Ukraine's systematic drone campaign has forced Moscow to suspend commercial shipping through the Sea of Azov, severing a critical export artery for Russian oil, grain and fertiliser.
Russia has suspended shipping through the Don-Azov canal after Ukrainian drones targeted 90 vessels in less than a week. The overnight strikes hit 10 tankers, four ferries and a major oil refinery in Syzran. This effectively shuts down the export route connecting the Sea of Azov to the Black Sea via the Kerch strait.
The Sea of Azov is a vital waterway for Russian oil, grain and steel to reach international markets. Its closure strands exports from the Caspian Sea, which relies entirely on this route. “The Caspian Sea doesn’t have any connection to the world’s oceans. It has turned into a lake,” said Andriy Zagorodnyuk, Ukraine’s former defence minister.
The attacks are degrading Moscow’s ability to move sanctioned oil. Ukraine’s drone forces chief, Robert Brovdi, said the Russian shadow fleet was “noticeably shrinking” and could no longer use the Kerch strait. Video released by his unit shows crews abandoning damaged vessels fitted with protective cages, while two large oil spills were reported off Taganrog.
The maritime blockade is part of a wider economic and logistical squeeze that extends far beyond the Black Sea. Ukrainian forces have systematically dismantled Russian radar and air defences, enabling strikes on refineries as distant as Omsk, 2,700km from Ukrainian territory. Yevgeniya Gaber, a senior fellow at the Atlantic Council, noted the overarching strategy targets logistics and fuel supplies.
“There is not a single oil refinery that is unhit now. Maritime logistics in the Sea of Azov, all of this fits into the same strategy and operational concept, which is a strategic neutralisation of Russia,” Gaber said. The Syzran complex, which supplies the military and previously sent fuel abroad via the closed canal, was the latest facility hit. Residents reported loud explosions at 5am on Sunday, with thick black smoke rising above the industrial area.
The campaign simultaneously isolates Crimea, cutting off supply routes to turn the peninsula into what Gaber described as an “island”. A state of emergency is in effect following widespread electricity blackouts and acute petrol shortages that have collapsed the local tourist industry. The blockade has also halted the transport of grain stolen from southern Ukraine through the ports of Berdyansk and Mariupol.
President Volodymyr Zelenskyy has framed these strikes as “long-range sanctions” in response to Moscow’s refusal to end the war. While Vladimir Putin insists his military objectives remain unchanged, the economic toll on Russian logistics is mounting. Overnight, Russian attacks killed four civilians in Ukraine, including three in the Dnipropetrovsk region.
