TOKYO - The operator of the Fukushima nuclear plant yesterday admitted for the first time that radioactive groundwater has leaked out to sea, fuelling fears of ocean contamination.

Earlier this month Tokyo Electric Power (TEPCO) said groundwater samples taken at the battered plant showed levels of possibly cancer-causing caesium-134 had shot up more than 110 times in a few days.

"But now we believe that contaminated water has flown out to the sea," a TEPCO spokesman said yesterday.
