Summary
Ukraine launched a large-scale drone attack involving over 100 drones, reportedly hitting a Russian oil refinery in Ryazan and targeting Moscow.
Verified footage shows a fireball at the Ryazan site. Russia claimed to have intercepted 121 drones across 13 regions, denying significant damage.
Ukraine also alleged strikes on the Kremniy plant in Bryansk, which it says produces weapons components.
On the short term: maybe
On the long term: makes absolutely no difference. Some of the soot from those fires might actually settle in the soil and stay there for 100 - 1000 years, which is probably the least harmful way petro chems could be converted. The portion that would have been converted to plastics and rubber might be a grey zone, but not a large one, since a large portion of that is burned at the end of its useful life.
