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.

Unknown drones launched a massive attack on the Russian city of Sochi. As a result of the strikes, a fire broke out at an oil depot in the Adler district, according to Russian social media channels. The attack began around 2:15 AM local time.

More than three years into Russia's full-scale invasion, Ukrainians across the country retreat each night to bomb shelters and metro stations in a nightly ritual.
