Video clips published by independent journalists show large fires and huge clouds of smoke from the company's facilities in the cities of Krasnodar and Nevinnomyssk.

In addition, an oil terminal in the city of Armavir was reportedly attacked. One person was killed, according to the Russian governor.
Ukraine has not commented on the information.
