Fears over Japan nuclear plant cause people to leave Tokyo

Japanese engineers have spent a fifth day battling to avert a nuclear catastrophe at the Fukushima plant in the North East of the country - after another fire broke out in one of the reactors.

Plans to drop sea water onto the plant from helicopters - to cool down the reactors - was abandoned.

There have been raised radiation levels 155 miles south in Tokyo and people are leaving the city to move south to safety.
