Several improvised explosive devices were found at a substation near a coal-fired power plant in Germany on Tuesday and several power lines were damaged, police and a grid operator said.
Operator 50Hertz said there was a "brief interruption of service" but all lines are now back in operation at the Preilack substation, which distributes power from the nearby Jänschwalde power plant.
Police said no one was hurt.
The apparent aim was to trigger a large-scale power outage in the area around the nearby coal-fired power plant. According to initial findings, however, this did not happen.
The Cottbus police directorate stated that the police headquarters in Potsdam had taken over communications regarding the incident. The Brandenburg Interior Ministry also referred enquiries there.
