Europe's biggest nuclear plant left with ten days of power after shelling

Overnight shelling has cut the main powerline to Ukraine's Zaporizhzhia nuclear plant forcing it to switch to its emergency diesel generators.
The plant, which is Europe's biggest, needs a constant power supply to its six reactors to avoid nuclear meltdown.
United Nations' atomic watchdog is warning the plant now only has ten days of emergency power remaining.
The International Atomic Energy Agency is pushing for a protection zone to be set up to prevent further shelling.
