The refinery is among Russia’s 10 largest oil-processing facilities and is Lukoil’s second-largest refinery after its facility in Nizhny Novgorod.

The reported strike hit the TANЕCO oil refinery in Nizhnekamsk, a major industrial city in Tatarstan located hundreds of kilometers from Ukraine.

Russian authorities report a drone attack on Perm, where Lukoil's Permnefteorgsintez refinery is located. Air defences respond and flights are suspended at the local airport.
