The fire broke out during the night before Thursday at the B&T / Brügger & Thomet site on Tempelstrasse in Thun-Allmendingen, Switzerland. Bern Cantonal Police said arson is currently the leading suspected cause and are seeking witnesses. The fire brigade fully extinguished the blaze by late afternoon. Der Bund reports that an online video circulated by a left-wing grouping allegedly shows at least two black-clad individuals lighting and throwing an incendiary device toward a shelter with wooden pallets. The reported motive in the video is opposition to B&T's production of the LBD 40 rubber projectile launcher, cited in connection with French police use against protesters and earlier Gilets Jaunes calls in 2019 to blockade B&T. The article notes that the video's authenticity is unconfirmed and that police are examining it as part of the investigation.
