Russia's gasoline production has fallen to about 70 percent of domestic consumption levels by the end of August. Two industry sources attributed the drop directly to a series of drone attacks that forced major refineries to suspend operations.

Ukraine has increased strikes on Russian energy infrastructure in recent weeks. The attacks target facilities involved in fuel production and distribution.

The reduction in output comes as domestic demand remains steady. Shortfalls could lead to higher prices or rationing measures in affected regions.

Refineries hit by the strikes include some of Russia's largest facilities. Repairs and restarts are expected to take time, according to the sources.

This development adds pressure to Russia's energy sector amid ongoing conflict. Officials have not issued an official statement on the production figures.
