On Saturday, two drones hit an oil depot in the port city of Sevastopol on the Russian-occupied Crimean peninsula, AP News reports.
The city’s governor Michail Razvozjajev said the attack started a massive fire that burned down four oil tanks, but there were no casualties.
A third drone was shot down and a fourth was electronically deactivated, according to Crimea’s Moscow-appointed governor Sergei Aksyonov.
