"Ukraine's sabotage limiting the water supply to the republic through the North Crimea canal can only be qualified as premeditated action against the people of Crimea," Itar-Tass news agency quoted him as saying.
Ukrainian media reported today that authorities in Kiev had closed the lock valves of the canal, which supplies up to 85 per cent of the peninsula's water.
But Aksyonov vowed that Crimea would not run out of water as the region had emergency supplies and talks were being held with Ukrainian officials to find a solution.
Crimea also depends on Ukraine for its electricity supplies.
