Russian authorities attribute a massive oil depot fire raging near the Black Sea resort of Sochi to a drone attack allegedly carried out by Ukraine. Sochi’s nearby airport has suspended flights.

According to Krasnodar Region Governor Veniamin Kondratyev, drone debris hit a fuel tank, and 127 firefighters were tackling the blaze.

At least seven civilians were reportedly injured in the city, which has been repeatedly shelled by Russian forces. Ukraine’s State Emergency Service said three of the wounded were being treated in the hospital.

According to Russian authorities, the drone attack on the Sochi refinery was part of a larger wave of attacks launched by Ukraine over the weekend, with multiple installations targeted in southern Russian cities, including Ryazan, Penza, and Voronezh. The governor of Voronezh reported that four people were injured in one drone strike.

Meanwhile, local officials reported that a Russian missile strike devastated homes and civilian infrastructure in Mykolaiv, a city in southern Ukraine, BBC reported.

Russia’s defence ministry said its air defences intercepted 93 Ukrainian drones overnight, 60 of which were over the Black Sea region.

Ukraine’s air force said that Russia launched a barrage of 83 drones or 76 drones and seven missiles overnight. They managed to shoot down 61 of the aerial threats, but 16 drones and six missiles hit targets in eight locations.

This comes after a particularly deadly week for civilians in Ukraine, including an attack on Kyiv on Thursday that killed at least 31 people.

The Ukrainian officials said that more than 300 drones and eight cruise missiles were launched in the assault, making the attack one of the deadliest on the capital since Russia launched its full-scale invasion in February 2022.

After the strikes, Ukrainian President Volodymyr Zelensky called for stronger international sanctions on Russia this week, while US President Donald Trump condemned Russia’s actions in Ukraine and suggested new sanctions against Moscow were coming.
