Russia's Ryazan oil refinery, owned by Rosneft, has reportedly ceased operations following a drone strike on Sunday, according to a Reuters report, citing two industry sources familiar with the matter.
According to the report, the refinery's main CDU-6 unit and another primary unit, CDU-4, were halted after the attacks sparked a fire at the facility, affecting a combined processing capacity of 12 million tons of oil per year, accounting for 4.9% of Russia's total refining throughput.
The sources said that repairs of the affected units could last several weeks, adding to Moscow's growing fuel supply constraints.
The incident comes amid persistent Ukrainian attacks on Russia's energy infrastructure, which President Vladimir Putin said were aimed at sowing discontent within the country.
Rosneft did not immediately respond to' request for a comment on this story.
