Power restored to thousands of Berlin households after suspected attack on high-voltage lines.

Authorities said power was being restored Wednesday to thousands in Berlin after four days without electricity following a suspected attack on high-voltage lines; the federal prosecutor has taken over the investigation.

Power was being restored Wednesday to thousands of households in southwest Berlin after a multi-day outage in freezing temperatures. Officials said the loss of supply followed a fire on a bridge that carries high-voltage cables and is being treated as a suspected attack. The interruption left tens of thousands without power and required several days of repairs. The federal prosecutor's office announced it has taken over the investigation. Key facts: - About 45,000 households and 2,200 businesses lost supply on Saturday, affecting an estimated 100,000 people. - Service was being gradually reconnected on Wednesday, with remaining households reported as being brought back online by the power operator. - Investigators are considering a written claim of responsibility by a far-left group that said it sabotaged a gas-fired power plant, and the claim is part of the inquiry. - The federal prosecutor's office said it is leading the probe, citing suspicions of anticonstitutional sabotage, membership in a terrorist organization and arson. Summary: The outage caused multi-day disruptions for many households and some businesses and was described by officials as the city's longest blackout since the end of World War II. Repair work has allowed gradual reconnections while investigators pursue the claim of sabotage. The federal prosecutor's office is now handling the case and further procedural steps were announced as the investigation continues.
