Fire breaks out at Japan nuclear plant

Fire has again broken out at a quake-stricken nuclear plant in north Japan.



The blaze struck reactor four of the Fukushima Daiichi plant for the second time in two days.



Officials later said the blaze appeared to be out, but soon after smoke was seen rising from the plant.



Last Friday’s 8.9 magnitude earthquake and tsunami, which killed thousands of people has damaged the plant's cooling functions.



The site has also been hit by four explosions, triggering radiation leaks and sparking health concerns.
