On Monday, Russia said it would investigate the cause of a large fire that erupted in the early hours of the morning near the area of the Druzhba oil depot, an oil storage facility outside the city of Bryansk just 96 miles northeast of its border with Ukraine. Some reports have indicated it could be a possible attack by Ukrainian forces on the Druzhba pipeline, which sends oil from Russia to Europe through Ukraine and Belarus.

Explosions rocked the fuel facility and logistics hub near the Ukrainian border, the results of a reported missile strike. A second blaze raged close to the depot this morning, with unconfirmed reports it started at a military base holding ammunition.
