Rosneft's sprawling oil refinery in southern port town of Tuapse has been struck by Ukrainian drones once again, unleashing a huge fire and significant destruction, in what marks thethird such attack just this month.

"Another serious incident has occurred in Tuapse. A large-scale fire broke out at an oil refinery due to an enemy drone attack," Krasnodar region Governor Veniamin Kondratyev wrote on Telegram, amidlarge-scale evacuations of the civilian population from the area.

Regional aviation hubs in nearby Krasnodar, Gelendzhik, and Sochi were closed as a result of the blaze which sent a large black smoke plume into the air stretching for at least 100km, regional reports indicate.

"For the safety of residents living near the refinery, evacuations are underway. A temporary accommodation center has been set up at local School No. 6. I urge residents to follow all recommendations," the regional government statement continued.

The Ukrainian monitoring Telegram channel CyberBoroshno reported thatat least four tanks were burningat the refinery following the strike.

“If in previous attacks the tank farm was hit, this time the refinery itself was directly targeted… There is a possibility that the fire could spread to neighboring tanks,” the report said.

Reuters says that as a result of the several waves of attacks on Tuapse, operations at the plant have remained halted since April 16 - which was the first big strike of the month.

One is left wondering, what about Russian defensive measures and why have these failed so spectacularly? First, it should be noted that small drones have become efficient and their size advantage is seen in evading conventional radar and anti-air missiles, by and large. TASS only has this to offer by way of officialstatement:

"Intensive efforts are underway" to prevent Ukrainian strikes on Russian territory.

All details about targets hit by the Kiev regime are classified: "As for any information regarding targets hit as a result of strikes by the Kiev regime, the details are classified; we will not discuss them publicly at this time."
