Kyiv intelligence agencies clash over Russian plot, leaving three injured
A violent confrontation erupted in Kyiv between the Security Service of Ukraine (SSU) and Defence Intelligence of Ukraine (DIU) on September 2, 2026. The clash, which left three DIU officers injured, occurred during an operation to foil a suspected Russian FSB terror plot against a Russian opposition leader. The incident is linked to the earlier disappearance of Stepan Kaplunov, a deputy commander of the Russian Volunteer Corps. While the SSU claims it was attacked by armed men, DIU personnel were injured, and investigators from the State Bureau of Investigation (SBI) intervened to disarm both sides. The Prosecutor General’s Office has opened a criminal investigation into the armed attack on SSU officers.
