A major Moscow oil refinery owned by Gazprom Neft was hit by a Ukrainian drone, causing a blaze which has since been extinguished, according to the capital city's mayor, Sergei Sobyanin and a statement from the city emergency services, on Tuesday.
Sobyanin said that no one was injured in the attack on the refinery, which, according to Gazprom Neft, supplies more than one-third of the gasoline and diesel consumed in the Moscow region.
No further details were provided regarding damage to the facility or limitations on production as a result of the drone strike.
Ukraine has been intensifying attacks on Russian territory in what is now the fifth year of Russia's full-scale war on its neighbor, as its drone capabilities improve, putting energy assets within reach.
Ukraine says it is targeting Russia's energy infrastructure to deprive it of resources, some of which are used to fund the conflict.
Russian news agency Interfax reported separately that oil company Tatneft has introduced temporary limits on sales of gasoline and diesel. The company said it would only accept payment for fuel in cash, the article said.
The sale limit is 30 liters for gasoline passenger cars, 60 liters for diesel passenger cars and 300 liters for trucks.
