Power supply to Ukrainian nuclear plant in occupied region severed.

The Zaporizhzhia Nuclear Power Station in southern Ukraine, Europe's largest nuclear power station, was cut off from its external power supply on Monday, forcing the region to rely on emergency generators to cool the nuclear fuel. Russia and Ukraine each blamed the other for the power outage. The International Atomic Energy Agency head said the "nuclear safety situation at the plant [is] extremely vulnerable." The power plant has shut down six reactors but a constant supply of electricity is still required to keep the nuclear fuel inside cool and prevent a potential meltdown.
