What happened

Ukraine's General Staff said its forces struck the Ust-Luga oil-processing complex in Leningrad Oblast during overnight attacks that also hit the Ilsky refinery. This is a separate July event from the documented 27 March Ust-Luga fire and shutdown. Because the reviewed report did not establish the extent of damage or an operational halt, this record remains reported.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
