Leningrad Governor Alexander Drozdenko said on Tuesday that the Kirishi refinery - known formally as Kirishinefteorgsintez - had been targeted and that there was a fire at an industrial zone in ​the town of Kirishi.

Two sources, who spoke to Reuters on condition of anonymity ​due to the sensitivity of the situation, said that three of the four crude distillation units of ‌the ⁠refinery were damaged in the drone attack.
