Sweden has tightened security at its nuclear plants after explosives were discovered at Ringhals power station in the country's southwest. Police are investigating the possibility of sabotage.
Police said bomb sniffer dogs had detected the explosives during a routine check of Sweden's three atomic power plants on Wednesday. They were found attached to a truck in an industrial area within the Ringhals plant's perimeter, 70 kilometers (45 miles) south of Sweden's second-biggest city, Gothenburg.
Police spokesman Tommy Nyman said they were investigating but had no suspects. He said the driver of the truck had not been aware of the explosives and was not a suspect.
"An outsider has obviously placed [the explosives] on the truck," Nyman said. "We're talking to the truck driver and are trying to map out her movements within the premises throughout the day."
Police said a forensic analysis showed there was no risk of the explosion, because there was no detonator.
Four of Sweden's 10 nuclear reactors are at Ringhals, which is controlled by the energy companies Vattenfall and E.ON.
