Ukraine's June 20 Drone Campaign Struck Gas Infrastructure in Crimea, a Power Plant, and a Siberian Refinery — and Russian Oil Refining Has Hit a Two-Decade Low

Tyumen Oil Refinery (Western Siberia)

Ukrainian Armed Forces struck the Tyumen oil refinery, one of Russia's largest private refineries, located approximately 2,000 km inside Russian territory . Tyumen region governor Aleksandr Moor confirmed the attack. The strike reportedly hit processing equipment, further straining Russia's already diminishing domestic refining capacity .

Other targets in the same wave

The June 20 operation also struck a bridge across the Henichesk Strait (a key supply route to Crimea), fuel depots, and military logistics facilities in occupied territories .

Broader campaign context

Moscow Oil Refinery attacks (June 16–18)

Just days earlier, on June 16, Ukrainian drones struck the Gazprom Neft Moscow Refinery — which supplies up to 40% of the Moscow region's fuel — igniting a fire and forcing a halt in operations . A second strike hit the same refinery again on June 18 . The cumulative damage led Moscow to impose fuel rationing by June 19 .

Russian oil refining at two-decade lows

Ukraine's sustained campaign against Russian refineries — 16 strikes in May 2026 alone, eight of which hit Russia's ten largest refineries — has driven Russia's crude oil refining rates down to their lowest level in 20 years by June 2026 . Rosstat's official data showed a 9.2% year-on-year drop in refined product output as early as April, and the damage has only accelerated since . Russia has been forced to ban gasoline exports through July and increasingly export unrefined crude oil because functional refinery capacity is severely degraded .

The June 20 strikes demonstrate Ukraine's growing ability to hit targets simultaneously across three axes: (1) deep inside Siberia (Tyumen refinery), (2) Crimea's gas and power grid, and (3) occupied territory logistics. This multi-layer campaign is systematically reducing Russia's ability to produce, transport, and distribute fuel domestically and to its military forces.
