KYIV, Oct 21 – President Volodymyr Zelensky calls for an international observation mission to be sent to Kakhovka Hydroelectric Power Plant (HPP).

"We have information that Russian terrorists have mined the dam and units of the Kakhovka Hydroelectric Power Plant. This is one of the large power facilities. The dam of this hydroelectric power plant holds a volume of about 18 million cubic meters of water. If Russian terrorists blow up this dam, more than 80 settlements, including Kherson, could be hit by rapid flooding," he said on Thursday, in an address via video link to EU leaders meeting.

"The water supply to a significant part of southern Ukraine may be destroyed. This Russian terrorist attack may leave Zaporizhia nuclear power plant without water for cooling - water for the Zaporizhia NPP is taken from Kakhovka reservoir," the president said.
