Radioactive water is leaking into the sea from a 20-centimetre (8-inch) crack in a containment pit at Japan's quake-hit Fukushima nuclear plant, its operator Tepco has said.

The bodies of two workers killed by the tsunami which wrecked Japan's Fukushima Daiichi nuclear plant more than three weeks ago have been recovered.

Their remains were found last Wednesday but had to be decontaminated before they could be returned to the families.

Meanwhile, officials are still struggling to stop contaminated water leaking into the sea from a crack in reactor 2.
