Footage released on Telegram, a popular instant messaging service in Ukraine and Russia, showed a Russian warehouse 50 km from the Ukrainian border engulfed in flames. Huge plumes of black smoke rise from the Klintsy site in Bryansk Oblast, Russia under mysterious circumstances. The Russian military warehouse is believed to house dozens of vital equipment for the conflict in Ukraine.
The images show two major fires in the warehouse, both running parallel to each other.
Smoke is first seen rising above an awning before a closer shot shows the warehouse burning on two fronts.
The site appears abandoned as battle-damaged Russian repairs succumb to searing fires.
As Russia continues its fierce battle in the eastern regions of Ukraine, equipment shortages could have a devastating effect on their offensive operations.
Elsewhere, a huge cloud of smoke could be seen rising into the air today in the town of Avdiivka in southeastern Ukraine after an explosion.
The city is home to a chemical plant, the Russian news agency RIA quoted one of its journalists as saying.
Avdiivka became another burnt Ukrainian town after Russian attacks.
A Ukrainian social media site reporting on the war also posted video of a large cloud of smoke rising from what it said was the city.

Mr Gadai said: “Unfortunately, the enemy artillery is simply dismantling, floor by floor, buildings which serve as shelters.”
The town, which sits on the eastern bank of the Seversky Donets River, has been under relentless attack for several weeks.
And Mr Gadai said falling water levels made Ukrainian defenses farther from the front more vulnerable to attack from Russian forces who repeatedly tried to cross.
He added: “The river has gone down about 3 meters, maybe more, and so maybe there will be more attempts to cross the river and create a new enclave.”
