Kyodo News wrote:A vehicle of what appears to be right-wing campaigners tried to enter the radiation-leaking Fukushima Daiichi nuclear power plant, and then broke through the gate of the nearby Fukushima Daini power plant Thursday, the government's nuclear safety agency said.
The driver of the vehicle was later seized by police, and the agency said it ordered Tokyo Electric Power Co., the operator of the two plants in Fukushima Prefecture, to take all measures to ensure security especially from the viewpoint of nuclear material protection.
