Arson Attack on Swiss Arms Manufacturer B&T Triggers Security Debate

Bern cantonal police confirmed that an arson attack targeted the premises of defense manufacturer B&T AG in Thun on October 29, 2026. Security cameras recorded attackers throwing incendiary devices at the building, though no suspects have been detained so far. A claim of responsibility released on social media linked the action to youth protests in France.

The activists cited European solidarity with victims of police violence in France, where law enforcement utilizes B&T-manufactured grenade launchers. B&T stated that its launchers are designed for single non-lethal plastic rounds, but noted that French authorities deploy cheaper projectiles that tumble in flight and cause severe injuries. According to company management, Swiss police forces do not employ those lower-cost munitions.

Although the company had previously experienced paint attacks and threats against executives, management stated there were no prior indicators of an arson attempt. In response to the incident, B&T plans to install external fire alarms and artificial intelligence-supported surveillance cameras. Other Swiss arms and ammunition manufacturers are also reviewing their security precautions.

The incident has prompted reactions across the Swiss political spectrum. Pro Tell, a pro-gun organization led by Swiss People's Party National Councillor Walter Gartmann, called on the Federal Council to establish a support fund for targeted defense firms. Michael Götte, co-president of the Security and Business Working Group, noted that the industry has maintained heightened vigilance for several years due to recurring disruptions by political actors.

The Centre Party National Councillor Reto Nause characterized the attack as the work of the violent left and expressed hope regarding upcoming legal changes, stating: “I hope that the use of intelligence service tools to combat violent extremism will be permitted.” Social Democratic National Councillor Andrea Zryd condemned the attack and welcomed police efforts to identify the perpetrators. Data from the State Secretariat for Economic Affairs shows B&T exported over 100 million Swiss francs in arms and ammunition in 2025, ranking as Switzerland's fifth-largest defense exporter.
