An aftershock with a magnitude of six has rocked eastern Japan.


Meanwhile, the UN's nuclear watchdog says Japan's nuclear plants are 'safe and stable' - despite varying reports over radiation levels.

Authorities though are taking no chances - a 30 kilometre no fly zone has been imposed around the plant, while a hundred and forty thousand people across a 12 mile radius have been told to stay indoors.

The EU has agreed to carry out tests on nuclear power plants in the wake of the crisis.
