Radioactive water has leaked from a storage tank into the ground at Japan's Fukushima plant, its operator has said.

Tokyo Electric Power Company (Tepco) said the leak of at least 300 tonnes of the highly radioactive water was discovered on Monday.

The plant, crippled by the earthquake and tsunami in 2011, has seen a series of water leaks and power failures.
