A drone attack has hit a major Russian oil refinery near the border with Ukraine, the plant’s management said, sending a ball of flame and black smoke billowing into the sky and prompting the suspension of operations.
Officials at the Novoshakhtinsk oil refinery in Russia’s Rostov region said the first drone attacked at 8:40am (05:40GMT), hitting a crude distillation unit, triggering a blast and ball of fire.

Russian regions bordering Ukraine have reported attacks and shelling after Moscow sent its troops into its neighbour on February 24 for what it still calls a “special military operation”.
The refinery is in southwestern Russia, just 8km (5 miles) from the border with Ukraine.
“As a result of terrorist actions from the Western border of the Rostov region, two unmanned aerial vehicles struck at the technological facilities of Novoshakhtinsk,” a statement from the plant said.
“Staff have been evacuated and technological equipment has been stopped to assess the damage.”
There was no immediate comment from Ukrainian officials on the alleged attack.
Rostov’s Governor Vasily Golubev said the oil refinery suspended operations. He said fragments of two drones had been found at the refinery.
Footage posted on social media appeared to show a drone flying towards the refinery, before a large ball of flame rose up. Al Jazeera was not able to verify the authenticity of the video.
The refinery, which started operations in 2009, has an annual capacity of up to 7.5 million tonnes.
Russia’s energy ministry said the fire had not affected gasoline and diesel supplies to consumers in southern Russia.
