Japan firefighter's shock at nuclear plant damage

Power cables have been attached to all reactors at Japan's stricken nuclear plant, which was seriously damaged in the 11 March earthquake and tsunami.

Lighting is back on in one control centre, a boost for engineers working to restart the cooling systems.

One of the first firefighters to reach the plant, which was hit by a series of explosions, told the BBC of his shock on seeing the extent of the damage.

Narumi Suzuki said all the crew "knew the threat from radiation".
