Ukraine, Russia Risking Disaster While Combat Surrounds Nuclear Plant

Europe's largest nuclear power plant was captured by Russia in March, but Ukrainian operators still work at the plant.

Last week the plant was disconnected from the grid for 24 hours and had to rely on backup generators.

Russia and Ukraine have accused each other of shelling the site.

Recent video from inside the plant shows Russian military vehicles parked near reactors, raising the risk of accidental fires.
