Two petrol stations in the city in Ukraine's north-east were hit by Russian drones on Monday, which local officials say wounded two people. In another attack on a petrol station outside the city of Kryvyi Rih last week, three people were killed. These attacks began in April, primarily in regions on the front line, and are steadily growing more frequent. At the same time, Russia has endured two waves of severe fuel shortages across the country as a result of Ukrainian drone strikes on Russian oil refineries.
