Fears grow over earthquake-hit Japanese nuclear plant
Technicians are battling to stabilise a third reactor at a quake-stricken Japanese nuclear plant, which has been rocked by a second blast in three days.
The fuel rods inside reactor 2 at the Fukushima Daiichi plant have been fully exposed on two separate occasions, raising fears of a meltdown.
Seawater is being pumped into reactor to try to stop the rods overheating and Tokyo has asked the US for assistance in managing the crisis.
