Japan reactor leaks again

A nuclear reactor in the town that suffered Japan's worst nuclear accident has been shut down after a leak was discovered in its cooling system.

Officials said no radiation had been released and the plant in Tokaimura, north-east of Tokyo, posed no threat.

Two workers were killed and thousands of people exposed to dangerous levels of radiation last year in a processing plant in Tokaimura in an accident caused by the company disregarding safety rules.
