IAEA plans high-level nuclear safety meeting

The operators of the Fukushima nuclear plant crippled by the Japanese earthquake and tsunami say highly-radioactive water has for the first time been found outside one of the reactor buildings.

The leak in a tunnel linked to the No 2 reactor has raised fears of radioactive liquid seeping into the environment.

The International Atomic Energy Agency has announced a high level summit in June for political leaders to examine the safety of nuclear plants worldwide.

Yukiya Amano, Director General of the IAEA spoke to the BBC's Nick Gowing about the latest developments.

He started by asking him if he believed what he was being told by Tepco and by the Japanese government.
