Ukrainian President Volodymyr Zelensky will hold an emergency meeting of the National Security and Defense Council following the destruction of the Nova Kakhovka dam, the council's secretary, Oleksii Danilov, said Tuesday.

Evacuations from potential flood zones have already begun, according to Oleksandr Prokudin, the Ukraine-appointed head of the Kherson regional military administration.

Ukraine's military has blamed Russia for the destruction of the dam, while a senior Russia-installed official said its destruction was "a serious terrorist attack."
