French security forces detained a man on Tuesday over the burning of a historic lighthouse. The blaze occurred in the country's central region during disturbances that followed a weekend of nationwide protests. Authorities believe the detained man is connected to radical far-left movements, though that assessment had not been confirmed publicly. The arrest came as French authorities investigated the fire and the wider rioting. The report did not identify the man or specify the charges filed against him. It also did not provide evidence linking him directly to the arson. The investigation into responsibility for the lighthouse's destruction continued.
