Attacks? Russia’s biggest chemical plant burns down mysteriously after 6 were killed in unexplained fire at Russian defense research institute in Tver (videos)

Russia’s biggest chemical plant burns down in second mystery fire in a day.

Dramatic footage shows smoke billowing from the Dmitrievsky Chemical Plant in the city of Kineshma.

A huge blaze has broken out in one of Russia’s biggest chemical plants.

Dramatic footage shows smoke billowing from the Dmitrievsky Chemical Plant in the city of Kineshma, around 250 miles east of Moscow.

The site, the largest manufacturer of chemical solvents (butyl acetate and othe industrial solvents) in Russia and Eastern Europe and supplier of a wide range of chemical and petrochemical products in the paint and varnish, rubber, leather, and food industries in Russia and in the world, is around 950km from the border with Ukraine.

It is not currently known what caused the fire to break out – but it comes on the same day that a huge defence plant blaze broke out, killing seven people.

The blaze was at the Second Central Research Institute of the Ministry of Defence of the Russian Federation in Tver, which has been involved in the development of Iskander missiles used with deadly effect in Ukraine.

Initial reports said the fire started on the second floor of the top secret research institute.

Officials reports say 6 people were killed, 27 people had been injured and at least 10 people are still missing.

The cause was not clear but there were reports of “poisonous bluish-black smoke” and dramatic photos show thick plumes of dark smoke rising from the flames.

It was unclear if there were chemical releases before the fire or as a result of the raging inferno.

Flames quickly spread throughout the building due to the wooden flooring, reports said.

Eyewitnesses report that because of the smoke, people who were in the room could not evacuate and had to jump from the windows. [MirrorJPost]
