9/2/2026, 12:11:21 PM
Core Event
On September 2, Ukraine’s Security Service (SBU) and the Main Intelligence Directorate (HUR) announced that they had foiled an assassination attempt organized by Russia’s Federal Security Service (FSB) against a leader of a Russian opposition nationalist movement who was in Kyiv for Ukraine’s Independence Day celebrations on August 24. The agencies said the plot was neutralized but did not disclose the target’s name or details of the planned attack.
Background & Context
Since the start of the war, Russian opposition figures and volunteer units have occasionally operated from Ukrainian territory. The Russian Volunteer Corps (RDK), a formation of Russian citizens fighting alongside Ukrainian forces, has been a focal point of such activity. The individual identified by Ukrainian media as the likely target is Stepan Kaplunov, deputy commander of the RDK. Kaplunov had reportedly gone missing near his home days before the Ukrainian security services announced the foiled plot, prompting the RDK’s chief of staff to involve Ukrainian investigators.
Key Figures & Groups
- Security Service of Ukraine (SBU) – Ukraine’s domestic intelligence agency, responsible for counter-intelligence and counter-terrorism operations.
- Main Intelligence Directorate (HUR) – Ukraine’s military intelligence service, cooperating with the SBU on the operation.
- Federal Security Service (FSB) – Russia’s primary security agency, alleged to have organized the assassination attempt.
- Stepan Kaplunov – Deputy commander of the Russian Volunteer Corps, identified by Ukrainian media as the possible target.
- Russian Volunteer Corps (RDK) – A paramilitary group of Russian nationals fighting on Ukraine’s side.
Timeline
- August 24 – The alleged target arrived in Ukraine to attend Independence Day celebrations.
- September 2 – The SBU and HUR publicly announced that they had disrupted the FSB-planned assassination plot.
Data & Statistics
- In a separate, earlier operation, Ukrainian authorities reported detaining more than 10 operatives linked to a Russian military-intelligence network that was preparing targeted killings of prominent figures in Ukraine; one armed suspect was killed during the arrest. This prior action underscores the ongoing threat of Russian-directed sabotage on Ukrainian soil.
Official Statements & Responses
Ukrainian officials described the September 2 announcement as part of an ongoing “operational and investigative” effort, emphasizing that the investigation remains active. They have not confirmed the identity of the intended victim, nor have they released information about any arrests related to the plot. Ukrainian media, citing unnamed sources from RBC-Ukraine, reported that the target was Stepan Kaplunov, but the SBU and HUR have not verified this claim.
Conflicting Reports & Gaps
- Target Identity: Ukrainian security agencies have not officially identified the intended victim, while Ukrainian media attribute the target to Stepan Kaplunov based on unnamed sources.
- Arrests and Details: No official information has been provided about whether suspects have been detained or how the plot was to be executed.
- Connection to Kyiv Shootout: Separate reports described a shootout in Kyiv involving armed personnel, but Ukrainian authorities have not linked that incident to the foiled assassination plot.
