Japan is to invest hundreds of millions of dollars into building a frozen wall around the Fukushima nuclear plant to stop leaks of radioactive water.

Government spokesman Yoshihide Suga said an estimated 47bn yen ($473m, £304m) would be allocated.

The plant was crippled by the 2011 earthquake and tsunami.
