A drone attack has ignited an oil refinery in the southern Russian region of Krasnodar, says governor Veniamin Kondratyev in a post on Telegram.

”The fire at the Afipsky oil refinery has been put out. I am grateful for our services’ swift and professional work,” he writes.

The governor stresses that no one was harmed in the attack, and that the firefighting service quickly succeeded in limiting the fire to an area of some 100 square meters. 

”No people were injured. I have full control of the situation,” the governor writes.

According to news agency Reuters, the Afipsky oil refinery lies 50 miles east of the Black Sea port of Novorossiysk, one of Russia’s most important oil export gateways.

Kondratyev does not comment on who he thinks is responsible for the drone attack.

Russian politicians and government officials have accused Ukraine of week-long drone attacks on select Russian targets.

On Saturday, governor of the Pskov region Mikhail Vedernikov blamed Ukraine for a drone attack which caused an explosion on a oil facility.

On May 3, a drone exploded over the Kremlin, which holds the offices of Russian President Vladimir Putin. Russia also puts Ukraine behind this attack.

Last week, The New York Times wrote that the attack on May 3 was likely orchestrated by one of Ukraine’s special military and intelligence units.

There have been no official confirmation on the report.
