A Ukrainian drone struck an oil storage depot in western Russia on Friday, causing a massive blaze, officials said.
Four oil reservoirs with a total capacity of 6,000 cubic meters (1.6 million gallons) were set on fire when the drone reached Klintsy, a city of some 70,000 people located about 60 kilometers (40 miles) from the Ukrainian border, according to the local governor and state news agency Tass.
