A high-ranking Swiss military officer has been recalled from his post at the Organization for Security and Co-operation in Europe (OSCE) in Vienna. The reason is a serious suspicion of passing information to Russian authorities. The affair has rocked Swiss diplomacy at a politically sensitive time, as Switzerland prepares to take over the chairmanship of the OSCE in 2026. The military justice system has launched an investigation to clarify the scope of the case.
