“The south-east of Ukraine is an industrial region where there are many chemical enterprises, and it is enough to organize some kind of provocation, to blow up a container with chlorine or ammonia, to cause a man-made disaster,” TASS quoted him as saying.

According to Shulgin, the risk of such provocations is increasing.

“As the encirclement around the nationalist battalions in the Donbass tightens, ... they will take any action,” he summed up.

Earlier, Lieutenant Colonel of the People's Militia of the LPR Andrey Marochko said that a tank with nitric acid was blown up in Rubizhne.

He urged the public to find shelter, prepare soda-soaked masks, and close doors and windows tightly.

According to the Russian Investigative Committee, more than 40 thousand tons of sulfuric, hydrochloric, nitric acids and ammonia remain on the territory of Zarya.
