Police and the Japan Coast Guard conducted a joint drill Saturday to prepare for a possible terrorist attack on the Fukushima No. 1 nuclear power plant.
About 150 officers and other people, including members of a special assault team of the police, participated in the drill at the Fukushima No. 2 nuclear power plant, about 10 km from Fukushima No. 1. Both plants are operated by Tokyo Electric Power Co.
The National Police Agency fears the stricken Fukushima No. 1 could make for a tempting target for terrorists because the cooling systems there are still highly fragile.
The drill was conducted on the assumption that three terrorists were hiding in a cargo ship berthed at a pier at the facility.
Members of a coast guard antiterrorism team boarded the ship from a helicopter and held two of the three attackers while police captured the third terrorist inside the plant's compound.
Under another scenario, members of a special assault team and other officers blocked terrorists who were attempting to storm into the nuclear plant in a vehicle with weapons and explosives.
