Explosion at Japan nuclear plant

A second explosion has hit the nuclear plant in Japan that was damaged in Friday's earthquake, but officials said it had resisted the blast.

TV footage showed smoke rising from Fukushima Daiichi's reactor 3, two days after an explosion hit reactor 1.

The latest blast, said to have been caused by a hydrogen build-up, injured 11 people, one of them seriously.

Officials said the reactor core was still intact, and that radiation levels were below legal limits.

But the US military, which has been helping the relief effort, said it had moved away from the area after one of its aircraft carriers detected low-level radiation about 100 miles (160km) offshore.

Technicians have been battling to cool three reactors at the Fukushima Daiichi plant since Friday, when the quake and tsunami combined to knock out the cooling system.

 Evacuations

The government said an operation pumping seawater into the reactors to help lower the temperature was still going on despite the explosion.
