Belarusian border guards detain cargo being illegally transported across the Dnieper section. However, the contraband turns out to be one of the anti‑aircraft missile systems stolen in Ukraine. To investigate this case, OSAM — a separate service for active operations — is involved. In addition, the Ukrainian side sends its own agent to participate in the investigation. The MANPADS must not be let loose, but there is no trust between the parties.
