A Russian-installed official in the town of Nova Kakhovka said on Tuesday residents of around 300 houses had been evacuated after a nearby dam was breached, state-owned news agency TASS reported.

TASS also quoted Nova Kakhovka's Russian-installed mayor Vladimir Leontyev as saying that part of the town had been disconnected from power supplies for safety reasons. (Reporting by Reuters; Editing by Andrew Heavens)
