Russia's Tuapse refinery ablaze again following Ukrainian drone strike

Last week, local residents were urged to stay indoors, keep windows shut and wipe down surfaces after byproducts from fires caused by earlier drone attacks mixed with rainfall to create a "black coating" in areas around the terminal, local authorities have said.

The Tuapse refinery has annual production capacity of about 12 million tonnes, or 240,000 barrels per day, turning out naphtha, diesel, fuel oil and vacuum gasoil.
