On Saturday, a massive fire erupted at an oil depot in Sevastopol, Crimea after it was hit by two of Ukraine’s drones, according to the Moscow-installed governor of the port city. Tensions between Ukraine and Russia have been escalating, with the Ukrainian government accusing Russia of sending military forces into the country’s east and south. The cause of the fire is still under investigation, and it is unclear what the impact of the fire will be on the region.
