View this signal on the map

On 9 September 2025, unidentified perpetrators deliberately set fire to cables attached to two high-voltage electricity pylons in Berlin’s Johannisthal district. The attackers reportedly wrapped chains around the cables and used gasoline to ignite them, causing short circuits that disabled two 110-kV transmission lines. At 05:09, approximately 50,000 households and commercial customers lost electricity across Johannisthal, Adlershof, Grünau, Bohnsdorf and surrounding districts. Public transport, traffic signals and businesses at the Adlershof Technology Park were affected. An anonymous anarchist group published a statement claiming responsibility and identifying the technology park as its intended target. Stromnetz Berlin restored electricity to all affected customers by 11 September, after approximately 60 hours. In March 2026, German authorities searched properties linked to four suspects as part of an ongoing investigation. No evidence established Russian state direction of the attack.
