"A fuel tank is on fire near Manganari Brothers Street in Kazachya Bay. According to preliminary information, the fire was caused by a UAV hit ... The fire area is about 1,000 square meters [10,764 square feet]," Razvozhayev said on Telegram on Saturday morning.
In a later post, the governor said that nobody was injured in the incident and that civilian infrastructure was not affected.
According to Razvozhayev, the fire has not been contained yet, and there are currently 60 firefighters working on the site. A fire train is expected to aid in extinguishing the blaze.
Later, the governor added that a total of four tanks were damaged at an oil depot in Sevastopol after a drone attack.
"The four fuel tanks that were hit are practically burnt out already … Based on what can be seen, the fire started at two different locations, which suggests there were two unmanned aerial vehicles," Razvozhayev told reporters.
The blaze is expected to be put out by 6 pm local time (15:00 GMT), the governor said, adding that the fire is "almost completely localized" and the intact fuel tanks are being kept away from the flames and cooled.
