Japan's nuclear clean-up suspended over radiation levels

Operators of Japan's Fukushima nuclear plant have suspended an operation to clean contaminated water hours after it began due to a rapid rise in radiation.
Some 110,000 tonnes of water have built up during efforts to cool reactors hit by the 11 March earthquake and tsunami.
The contaminated water, enough to fill 40 Olympic-sized swimming pools, has been at risk of spilling into the sea.
