Ukrainian drones have struck nearly every major Russian refinery. Which facilities have yet to be hit?

Ukrainian forces have been systematically targeting Russian oil refineries.

By the end of May 2026, the Reuters news agency reported, not a single major refinery in the European part of Russia had escaped a Ukrainian drone attack.

Many have been hit multiple times.

The strikes have forced plants to cut or halt production, setting off a large-scale fuel crisis across the country.
