Drone attacks cause chaos in Russian oil industry.

A drone attack caused a fire at the Ilsky oil refinery in southern Russia, but emergency services were able to extinguish the fire within two hours. The refinery, which has a processing capacity of 6.6 million tonnes per year, is now working normally. The cause of the fire is being assessed. This comes after a fuel depot caught fire near a bridge linking Russia's mainland with the occupied Crimea peninsula. There were no casualties reported in either incident.
