Monitors from the OSCE Special Monitoring Mission (SMM) to Ukraine have reported the militants want to flood the Yunkom mine in the town of Bunhe, which is 43 kilometers north-east of the temporarily occupied city of Donetsk.
"Staff at the Yunkom mine in Bunhe (former Yunokomunarivsk, non-government-controlled, 43km north-east of Donetsk) told the SMM that some of the mine's pumps would be shut off around April 14, and thus the mine would be gradually flooded. (In 1979, a nuclear device was reportedly detonated in a capsule inside the mine. Staff from the mine also told the SMM that it is not clear how possible leakages or increased pressure from the flooding of the mineshaft could threaten the integrity of the capsule)," the mission said in an update based on information received as of 19:30, April 11, 2018.
"However, the deputy chief engineer and three other persons (man and two women) said the current status of the capsule is not known, and it is not clear how possible leakages or increased pressure from the flooding of the mineshaft would affect the capsule's integrity," the monitors said.
