MOSCOW: NORSI, Russia’s fourth-largest oil refinery, has shut its main primary CDU-6 unit after a Ukrainian drone attack on Wednesday, two industry sources with direct knowledge of the situation told Reuters on Thursday. Virtually all major refineries in central Russia have been forced to halt or scale back output after Ukrainian drone attacks in recent days, Reuters has reported. Russia’s second-largest producer of gasoline, NORSI can process 16 million metric tons of oil per year, equivalent to some 320,000 barrels per day.

The Moscow Oil Refinery temporarily halted its processing operations following a large-scale Ukrainian drone attack on May 17, Reuters reported, citing industry sources.
