A refinery in the Nizhny Novgorod region has suffered such damage (t.me/yigal_levin/63683) that the plant will now not operate at full capacity.
OSINT investigator Neonhandrail established (twitter.com/neonhandrail/status/1767404444797337955) the drone's point of arrival. The fire broke out right at the vacuum units.
Moreover, according to Governor Gleb Nikitin's explanation, the oil refining equipment caught fire. This refinery produces 11% of all Russian gasoline, and the annual refining capacity is 16-17 million tons of Russian oil.
