Ukraine will have to stop water supply to territories in Luhansk region not controlled by Kyiv, Ukrainian Deputy Minister for Temporarily Occupied Territories and Displaced Persons Heorhiy Tuka said.

"Supplying civilians with drinking water is a state's obligation. This is a humanitarian component, which is under permanent control of international organizations," Tuka said. "Our international partners regularly help us resolve this issue: the government of Switzerland has been providing chemicals and special sand, and the International Committee of the Red Cross has paid for the necessary amount of water for Luhansk region to make sure that the heating systems are filled during the winter period," Tuka said on Facebook on Wednesday.

The Trilateral Contact Group for settling the conflict in Donbas reached agreement in Minsk on setting up a Ukrainian enterprise to settle accounts for water consumed in the territories not controlled by Kyiv, Tuka said. Ukraine has also repaired the pipelines and installed modern meters, but the uncontrolled territories have been "absolutely ignoring" the problem, he said.

"Their representatives have just stopped responding to telephone calls and have not come to receive electronic keys from the meters. At the same time, the 'authorities' of the certain areas in the Luhansk region have been consistently reducing the amount of water in their requests," Tuka said.

Water is currently supplied to residents in these areas "only for three hours every other day," he said.

The authorities are so seeking to sow hatred toward Ukraine among the local residents and to have a pretext for accusing Kyiv of "genocide of the Russian people," he said.

"The agreement's validity will expire on December 1, after which Ukraine will have no other choice but to cut off water supplies completely," he said.
