No radiation was released from a Russian attack at Europe's biggest nuclear power plant in Ukraine and firefighters have extinguished a blaze at the facility, officials said, as Russian forces pressed their campaign to cripple the country despite global condemnation.

In the early hours of Friday morning, a fire broke out in a training building outside the Zaporizhzhia nuclear power plant, after it was shelled by Russian forces, Ukrainian authorities said.
