What the 20 September strikes showed on both sides
Summary
A look back at reported attacks on Ukrainian infrastructure and Russian oil refineries, as recorded in the days before 21 September 2025.
What did the previous day's attacks reveal as of 21 September 2025? Reports from 20 September described strikes in both directions, hitting energy and residential targets alike.
In Ukraine, a Russian drone and missile attack on critical infrastructure and residential buildings across the country killed at least three people and injured more than 30. The reported targets spanned infrastructure and homes, so the harm fell on civilians as well as on utilities.
In Russia, a Ukrainian drone attack on oil refineries in Novokuybyshevsk, in Samara Oblast, and in Saratov, in Saratov Oblast, killed four people and injured one.
Taken together, the reports show a pattern in which each side struck energy-related facilities deep inside the other's territory. Both reports counted casualties from a single day of attacks. The reports give no further detail on the damage to the facilities or on any response, so the scale of the effect on energy supply remains outside what was reported on 20 September.
