Thousands of people have marched in Tokyo calling on the Japanese government to ban nuclear power. 

Tomorrow marks the second anniversary of the earthquake and tsunami which caused the world's worst atomic disaster in 25 years. 

More than 160,000 people fled their homes after the meltdown at Fukushima nuclear plant and many of them will never be able to return. 

A further 15,000 people were killed in the earthquake and several thousands more are still unaccounted for.
