Kyiv Mayor Klitschko warns of evacuations if power lost

Kyiv residents should be prepared to leave the city if there is a total loss of power, its mayor has said.

In recent weeks millions of Ukrainians have intermittently been left without electricity and water, as Russian air strikes target vital infrastructure.

Rolling power cuts are also in place to avoid overloads and to allow for repairs.

Some 40% of Ukraine's energy system has been damaged or destroyed by Russian attacks on power plants and lines.
