A 48-year-old man was arrested on Tuesday near the Weisweiler power plant in western Germany, suspected of carrying out a series of sabotage attacks on the country's electricity grid. Police said the suspect was carrying explosives at the time of his detention, and further explosives were found rigged in a nearby tent. The suspect had reportedly claimed responsibility for the attacks, which involved using rockets to shoot wires across high-voltage cables, in letters to German media. Germany's Interior Minister Armin Schuster admitted the incidents could have led to a regional blackout.
