Ukrainian attack sparks blaze at Russian oil depot as countries trade strikes

Video shows black smoke pouring from facility in Sochi, while Russian attack on Mykolaiv wounds seven people

An overnight Ukrainian drone attack on an oil depot near the Russian Black Sea resort of Sochi ignited a raging fire, as the two countries traded strikes at the end of one of the deadliest weeks in Ukraine in recent months.

More than 120 firefighters worked to put out the blaze, said the regional governor, Veniamin Kondratyev, as emergency officials reported a fuel tank with a capacity of 2,000 cubic metres (70,000 cubic feet) had burned before it was extinguished.
