quake-stricken nuclear plant in Japan has been hit by a third explosion in four days, amid fears of a meltdown.The blast occurred at reactor 2 at the Fukushima Daiichi plant, which engineers had been trying to stabilise after two other reactors exploded.
The protective chamber around the radioactive core of reactor 2 has been damaged and radiation levels near the plant have risen, officials say.
The crisis was sparked by a 9.0-magnitude quake and tsunami on Friday.
Thousands of people are believed to have died, and millions are spending a fourth night without water, food, electricity or gas. More than 500,000 people have been left homeless.
