Japan steps up cooling operation - Video
Japan says it is stepping up efforts to cool overheating fuel at the tsunami-hit Fukushima Daiichi nuclear plant. Helicopters dumped tonnes of sea water to try to prevent a meltdown of fuel rods, and media reports said water cannon had now joined in the operation on the ground. Following the crisis, China suspended approval for new nuclear plants. The confirmed death toll from Friday's 9.0 magnitude quake, which triggered the tsunami, has risen above 5,000. Police say more than 5,400 people are confirmed dead and about 9,500 more are still missing. [Professor Andrew Sherry explains the situation as helicopters spray water to cool nuclear reactors]
