Urgent UN warning as Ukraine nuclear plant loses power

BBC LIve Summary

More than 80 Russian missiles have been fired at cities across Ukraine in a sustained overnight barrage - the biggest for weeks.

At least nine people have been killed and power at Europe's largest nuclear plant in Zaporizhzhia has been lost.

Ukraine's military says eight drones were also involved and President Zelensky decried Moscow's "wretched tactics".

In a town in the western region of Lviv, at least five people have been killed, with other victims feared trapped under rubble.

Emergency services in Kyiv are at the scenes of blasts in western and southern districts of the capital - much of the city has been left without electricity.
