A Ukrainian drone strike has sparked a fire at the Tyumen refinery in western Siberia, local Russian authorities said on Saturday.

The attack on a facility more than 2,000 km from Ukraine underscores the increasing reach of Kyiv’s long-range drone campaign against Russian energy infrastructure.

Emergency services are working at the scene, Tyumen region governor Alexander Moor said, without giving further details.

The refinery has a nominal capacity of around 8 million metric tons per year. It processes roughly 6 million tons of crude annually, producing about 0.5 million tons of gasoline and 2.5 million tons of diesel.
