The Russian emergency authorities said that a huge fire broke out, on Monday, in an oil storage facility and logistics center in the Russian city of Bryansk.
Video footage on social media showed a wall of flames billowing around a giant fuel tank after what appeared to be two explosions about 100 miles northeast of Ukraine.
Another video showed what appeared to be another fire burning at a second site in Bryansk.
Reuters reported that it was unable to verify the clips.
The Russian Emergencies Ministry said the accident was unharmed, and it would be investigated.
The ministry said there was no need to evacuate any parts of the city of Bryansk, which has a population of 400,000, after the fire broke out around 2 a.m. local time at the Transneft Bryansk-Druzhba facility owned by the Transneft oil pipeline company.
The depot is also used to support the forces of Russian strongman Vladimir Putin, According to the Telegraph.
Rob Lee, of King’s College London’s Department of War Studies, told the outlet that the targets were within the range of a Tochka-U ballistic missile if it was deployed near the border.
There has been unconfirmed speculation on social media that the fire was the result of a Ukrainian missile strike. But there was no immediate comment from Kyiv, which denied or did not respond to earlier suggestions that Ukrainian forces had hit targets inside Russia during the invasion.
Last week, Russian officials claimed that Ukrainian helicopters had hit apartment buildings and injured seven people in the Bryansk region.
The Ukrainian Defense Ministry did not respond to a request for comment on the claim at the time.
Bryansk is an administrative center 96 miles northeast of the Ukrainian border and about 240 miles from Moscow.
