The grenades exploded on several occasions at the Russian military base in Siberia on Monday, Reuters writes. Pictures show a huge explosion against the sky like a firework, followed by black smoke.
A total of 11,000 Russians were evacuated from parts of the city of Atjinsk in the Krasnoyarsk region, located near the explosion site. According to a source to the Russian news agency TASS, a Russian soldier was killed, but a source at the Ministry of Defense denies the information. A total of eight people must have been injured.
The aluminum plant in Atjinsk, the world's largest outside China, was forced to interrupt its production in connection with the explosions.
