Moves towards restarting nuclear reactors in Japan have provoked an angry protest from people worried about a repeat of the Fukushima disaster.
They disrupted a hearing in Tokyo by a panel of experts reviewing the results of stress tests on two reactors that may be restarted.
The activists were protesting against a decision not to allow civilian observers to take part. One of the experts involved, Professor Hiromitsu Ino of Tokyo University, said it was wrong to have the public excluded. He and a colleague withdrew from the meeting when it reconvened several hours later.
