Reports of a fire at the Moscow Ministry of Defence have been rejected by Russia.
Social media videos from late last night showed white smoke rising over the structure on Frunzenskaya Embankment.
The video’s original poster claimed that the “burning smell is awful.”
Initial reports said that a balcony of the Soviet facility was caught in flames, however officials later denied this.
‘The presence of a fire has not been confirmed, as no fire was detected by the fire brigade upon arrival,’ the Emergencies Ministry stressed.
‘Neither is there any information about victims.’
It is yet unclear if authorities were seeking to cover up the incident to avoid panic among residents.
The ‘Liberty of Russia’ Legion, which is made of Russian citizens opposing the war and the Kremlin regime, shared a picture of the alleged fire on Twitter.
Though yet unverified, it showed smoke filling up the sky above the capital.
‘A nighttime fire in Moscow. Smoke is in Defence Ministry. Unknown patriots are smoking?’ the tweet read.
It comes amid high alert over sabotage attacks on key facilities in Russia by anti-Putin partisans.
Earlier this month, a small explosion apparently caused by two drones took place at the Kremlin.
At the time, Moscow described its as an attempt on the life of the president, and it blamed Ukrainian and the US intelligence for being behind the attack.
