The Collective Security Treaty Organization (CSTO) will hold its Indestructible Brotherhood 2026 peacekeeping drills in Belarus in October, CSTO Secretary General Talatbek Masadykov said in an interview with media outlets. "In October this year, the Indestructible Brotherhood 2026 command and staff exercise with the CSTO peacekeeping forces will take place on the territory of the Republic of Belarus," he said. The organization will also coordinate activity in the sphere of preventing biological threats to create a reliable CSTO biological security system, he said. "We will continue practical measures in the format of special operations codenamed Mercenary, Channel, Illegal Agent and Proxy," he added. The post-Soviet security bloc will continue actively providing information-analytical and prognostic support, coordinating efforts of the civil scientific and expert community, expanding the presence of CSTO themes in social networks and bolstering the organization’s image, Masadykov said.
