Authorities in Sochi detained two girls and a young man who filmed a video against the backdrop of a burning oil depot, according to the Krasnodar Oblast Ministry of Internal Affairs.

The detainees traveled to Sochi from Nizhny Tagil, the ministry reported. Officials issued a protocol against one of the detained individuals under the article concerning “failure to comply with rules of conduct in case of emergency situation or threat of its occurrence.”

This violation carries penalties ranging from a warning to fines between 1,000 and 30,000 rubles ($12-$375).

Adler oil depot in Sochi, southern Russia, burned after Ukrainian drones struck overnight on 3 August, igniting a 2,000 cubic meter fuel tank around 530 km from the frontline. The strike forced a halt to flights at Sochi airport.

Telegram channels reported, citing eyewitnesses, that approximately 20 explosions were heard in Sochi. The oil depot includes 41 tanks with a combined capacity of around 31,200 cubic meters.
