When bullets start flying between your own security services in the middle of the capital, you have a massive problem. That is precisely what happened on September 2, 2026, in a residential courtyard in Kyiv's Dniprovskyi district. Operatives from the Security Service of Ukraine, known as the SBU, and fighters from the Main Directorate of Intelligence, or HUR, turned their weapons on each other. Three security officials were wounded.
President Volodymyr Zelenskyy didn't mince words, calling the incident utterly disgraceful. If you want to understand why two pillars of Ukraine's defense establishment started shooting at compatriots while Russian missiles were falling overhead, you have to look past the official press releases.

The Spark Behind the Kyiv Gunfight
The violence didn't happen in a vacuum. At the center of the storm is Stepan Kaplunov, the deputy commander of the Russian Volunteer Corps. The RVC consists of Russian nationals fighting alongside Ukrainian forces and operates under the umbrella of HUR.
According to legal representation and military intelligence sources, Kaplunov was detained near his home on August 23 and held for days without formal legal procedures or immediate public tracking. The SBU claims they picked him up during a counter-sabotage operation, acting on intelligence that he had contacts with Russia's Federal Security Service and was allegedly linked to a planned plot against a Russian opposition figure.

Kaplunov's supporters and HUR-linked units saw it differently. They viewed the detention as an illegal abduction carried out by a rival domestic agency. When HUR personnel tracked down the location where SBU operatives were conducting a search with Kaplunov present, things escalated instantly. Tensions flared, vehicles blocked roads, masked men squared off, and the SBU's Alpha special forces opened fire.
Turf Wars and Institutional Friction
This wasn't just a random misunderstanding between police officers. It dragged a long-simmering institutional rivalry out into the open.
The SBU handles domestic security, counterterrorism, and internal threats. HUR operates primarily as a military intelligence arm focused on foreign operations, cross-border raids, and managing allied paramilitary groups like the RVC. In practice, their jurisdictions frequently overlap, especially when dealing with volunteers, foreign fighters, and counter-intelligence inside the country.
Competition for resources, operational autonomy, and influence within Kyiv's security hierarchy has always run deep. When these agencies operate with massive autonomy and high-powered weapons during wartime, overlapping mandates create dangerous friction. Pointing guns inward instead of outward provides an alarming snapshot of institutional decay that any wartime government must stomp out immediately.
The Immediate Fallout and Accountability
President Zelenskyy acted swiftly after the gunfire stopped. He announced dismissals within the security apparatus, targeting high-ranking officials from both organizations to signal that internal lawlessness will not get a pass. The State Bureau of Investigation and the Prosecutor General's Office launched full-scale criminal probes to sort out who fired first and whether the initial detention procedures crossed legal boundaries.
The SBU released footage of Kaplunov discussing contacts with Russian handlers, while his defense team and military intelligence allies maintained that the interrogation was coercive and designed to undermine HUR's leadership.
Ultimately, the firefight serves as a stark reminder that managing a wartime state involves keeping internal factions aligned. When elite forces clash over turf in a sleeping neighborhood, the threat isn't just external. Accountability must be swift, transparent, and uncompromising if public trust is going to hold.
