Donetsk, May 3 – DAN. Kiev's strikes on Donbass territory have led to flooding in seven mines, endangering the fragile ecology of the coal-reach region.

He said the most disturbing objects were ionizing radiation sources containing radioactive elements, as they were no longer duly maintained.

Tokarev said the Prosecutor General's Office was looking into the situation to decide whether a criminal case should be filed.

"Mining affected around 20 thousand square kilometers of Donbass territory. Mining allotments are located in densely populated areas with dense development."

Donetsk water treatment plant, located between Yasinovataya and Kiev-controlled Avdeyevka has long been a trouble spot on the contact line in Donbass. It supplies water to both sides of the contact line, DPR-controlled Donetsk and Yasinovataya and Vasilyevka and Spartak villages, and Kiev-controlled Avdeyevka, Krasnogorovka and Verkhnetoretskoye village. DFS often comes under Ukrainian forces fire, though it stores chlorine. *ot
