KIEV, May 19 – The head of the Donetsk regional military-civilian administration, Oleksandr Kikhtenko, says that almost 60% of mines in the territory controlled by so-called Donetsk People's Republic militants have been flooded and are unlikely to be restored.

"Almost 60% of mines in the territory uncontrolled by Ukraine are unfit for work, they are flooded. And it is almost impossible to restore their operation," Kikhtenko said.
