The latest explosion follows two incidents which happened in Russia last month. Massive explosions were first recorded at a military ammunition depot near the city of Achinsk in eastern Siberia's Krasnoyarsk region.

That was followed by a deadly explosion at a military weapons testing range in Nyonoksa, in the far northern Arkhangelsk region left at least five people dead. Officials said the explosion occurred while engineers were testing "a nuclear isotope power source" for a rocket and were thrown into the sea by the explosion.
