Berlin's unsolved arson attack deepens political crisis

An arson attack last January plunged Berlin into its worst blackout since World War II—45,000 homes and 2,000 businesses lost power for nearly a week in freezing cold. The attackers remain unidentified. Mayor Kai Wegner faced resignation calls after playing tennis during the emergency. His withdrawal from September's election shows how the unresolved incident continues to undermine public confidence in the city's leadership.
