February, 8
A very powerful explosion (videos available) was reported in Donetsk on 8 February. Later it was said  that a chemical plant  in Donetsk  was hit by Tochka U  missile (fragments shown by Basurin). Preliminary information is that nobody was killed in that explosion. Investigators were on the scene next morning, but the area was further shelled by Ukraine; thus fragments were found and shown next morning. The plant traditionally produced explosives for mining and defense, and utilized old munitions, according to old Ukrainian sources. DPR sources say that the plant is currently producing paints and dry mixes.

It is because this is where the Ukrainian government housed a depostitory of used nuclear waste.....SO...In effect Kiev is trying its hardest to detonate what is known as a DIRTY NUCLEAR BOMB.....

 * ''The radiation background level could have grown in Donetsk due to the powerful explosion in the State Factory of Chemical Products, because a nuclear waste depository is situated there, claimed executive director of the state enterprise East Ukrainian Ecological University Dmitriy Averin according to OstrovV website.
 * ''“It is not reliably known what exactly happened there (at the chemical works in Donetsk. – ed.). This is the third explosion occurring in its territory. It is there that one of the nuclear waste depositories of the Ministry of Defense of Ukraine is situated”, – the expert remarked, having added that there is a chance of destruction of this depository.
 * ''Averin also said that no one is monitoring the environment in the “occupied territories”, as he put it, that is why people might know nothing about the contamination.
 * ''Fortunately, he is mistaken, but he could have unintentionally revealed the purpose of Ukrainian Army repeated attempts to turn the area of the chemical plant in Donetsk into a replica of the Moon surface.
