Ammon News - More than 120 firefighters were trying to extinguish a blaze at an oil depot in the Russian city of Sochi that was sparked by a Ukrainian drone attack, regional Governor Veniamin Kondratyev said early on Sunday on the Telegram messaging app.

In the Krasnodar region on the Black Sea where Sochi is located, a fuel tank with a capacity of 2,000 cubic metres (70,000 cubic feet) was on fire, Russia's RIA news agency reported, citing emergency officials.

The Russian defence ministry said in its daily morning report on Telegram that its air defence units destroyed 93 Ukrainian drones overnight, including one over the Krasnodar region and 60 over the waters of the Black Sea. Reuters
