Russia's Ryazan oil refinery has been shut down after a Ukrainian drone attack late last week, two industry sources told Reuters.
They said the refinery's oil storage facility had been set on fire. Among the damaged equipment were a rail loading rack and a hydrocleaner used to remove impurities from refined products.
"Rail loading equipment was damaged. "There were no rail cargoes, they stopped processing the oil," one of the sources said.
Another said loading had been suspended since Friday and also confirmed that the refinery was shut down due to the inability to ship oil products.
Rosneft, which owns the plant, did not comment on the matter.
Other industry sources said other oil refineries, including in Moscow, Nizhny Novgorod and Yaroslavl, could step in to provide the fuel.
The Ryazan oil refinery processed 13.1 million tons (262,000 barrels per day), or almost 5% of Russia's total refining capacity in 2024.
It produced 2.2 million tons of gasoline, 3.4 million tons of diesel, 4.3 million tons of fuel oil and 1 million tons of jet fuel.
