The incident occurred early on Wednesday morning in the Belgorod region.
A series of explosions have rocked an ammunition depot south of the Russian city of Belgorod, close to the Ukrainian border, after several villages in the same region have been hit with attacks that have been blamed on Kiev's forces.
The first powerful blasts were heard around 3: 30 am local time, with some reports saying air defenses had been activated. Several photos and videos showing a fire followed by secondary explosions, soon started making the rounds on social media.
According to the regional governor, Vyacheslav Gladkov, there was no reports of casualties or damage to civilian infrastructure, a local official said a local official had confirmed that an ammunition depot was burning near the village of Staraya Nelidovka, about 12 kilometers from the Ukrainian border.
The blaze was reported to have been contained by 6: 30 am, but the exact cause of the incident remains unknown.
Since the beginning of the Russian attack on Ukraine on February 24, numerous settlements in the Belgorod region have been hit by salvos, with several criminal cases subsequently opened. Local authorities accused Ukraine of shelling three villages, including the settlements of Zhuravlevka, Golovchino and Nekhoteevka, on Monday night.
Russia attacked the neighboring state in late February, after Ukraine failed to implement the terms of the Minsk agreements, first signed in 2014, and Moscow s eventual recognition of the Donbass republics of Donetsk and Lugansk. The German and French Minsk Protocol was designed to give the breakaway regions special status within the Ukrainian state.
The Kremlin has demanded that Ukraine officially declare itself a neutral country that will never join the US-led NATO military bloc. Kiev insists that the Russian offensive was unprovoked and has denied that it was planning to retake the two republics by force.
