A horror fire has erupted at a massive Russian oil refinery after a suspected Ukrainian drone attack. The sky over the Tuapse Oil Refinery turned red as a fire engulfed one of Russia’s major southern ports, resulting in the deaths of two children.

Veniamin Kondratiev, governor of the Krasnodar region, said two children aged 5 and 14 were killed in what he called a massive attack by Ukrainian drones on Tuapse. Two adults were also injured in the large explosions last night. Unverified images published by Russian media shows the night sky illuminated in red from the raging fire.

Eyewitnesses also shared dramatic images under a mile from the scene on Kavkazskaya Street. Sergei Boiko, the head of the Tuapse municipality, said fragments from the drone strike fell on enterprises at the port. He added no further information.

Ukraine has yet to comment on the incident. Russia‘s ⁠defence ​ministry said 207 Ukrainian drones were ​intercepted overnight.

Operated by LLC, the Tuapse Oil Refinery functions as an export hub for oil products and also handles dry bulk cargo, including coal and fertiliser.

The site also hosts a major oil refinery of the same name, owned by Rosneft, Russia’s largest oil producer.

This comes after Russia launched heavy drone and missile strikes on Ukraine overnight, killing at least 15 people and injuring at least 90, Ukrainian officials said.

Strikes on the capital Kyiv killed four people, including a 12-year-old boy, and three people were killed in Dnipro in the southeast, according to Oleksandr Ganzha, the head of the regional administration.

In Kyiv, Mayor Vitali Klitschko said 45 city residents were injured with one drone slamming into a 18-storey building.

A 77-year-old woman and a 66-year-old man were injured in a strike in Kharkiv, the head of the regional military administration, Oleh Syniehubov, said on Telegram.

Elsewhere, missile and drone attacks on the southern port city of Odesa killed eight people, the head of the city’s military administration Sergiy Lysak wrote on Telegram.
