On a quiet Tuesday morning in the Dniprovskyi district of Kyiv, the war came home in a way nobody expected. Officers from Ukraine’s domestic security apparatus, the SBU, faced off against soldiers from military intelligence, the HUR, with automatic weapons on a residential avenue. Three operatives were left bleeding on the asphalt, three individuals were detained, and President Volodymyr Zelenskyy was forced to condemn an absolutely disgraceful incident that laid bare the raw, unchecked friction between Kyiv’s rival espionage empires.
The confrontation on Yuriya Shumskoho Street was not a random flare-up of tempers. It was the explosive collision of overlapping mandates, bloated wartime budgets, and opaque jurisdictional lines that have defined Ukraine’s intelligence architecture since the 2022 full-scale invasion.

Anatomy of a Blue-on-Blue Firefight
The fuse was lit by the disappearance of Stepan Kaplunov, deputy commander of the Russian Volunteer Corps (RVC). The RVC is a paramilitary formation of Russian nationals fighting under the administrative umbrella of Ukrainian military intelligence. When Kaplunov vanished from near his home, his unit raised the alarm, claiming he had been abducted.
What followed was a bureaucratic and operational catastrophe. The SBU claimed it was executing an authorized counterintelligence operation to thwart an assassination plot orchestrated by Russia's Federal Security Service (FSB) targeting a Russian opposition figure. According to the SBU version of events, their investigative team was conducting a search at a residential address when a squad of armed men arrived, blocked their vehicles, and attempted to obstruct the lawful execution of their duties.

Military intelligence operatives saw it differently. Believing their man was being illegally detained or kidnapped by unknown actors—who initially did not identify themselves as state security—HUR-affiliated personnel rushed to the scene.
Initial local commander talks reportedly resulted in a temporary handshake agreement, but the situation quickly deteriorated. Reinforcements from the SBU’s elite Alpha special forces unit arrived, opened fire to suppress what they termed armed resistance, and began arresting members of the defense forces. By the time the State Bureau of Investigation (DBR) intervened to force both sides to unload their weapons, three HUR personnel had sustained injuries, including at least one severe arterial wound.
The Structural Disease Behind the Smoke
Incidents of lethal friction between Ukrainian security bodies are rarely discussed in public, but they are not entirely unprecedented. In the chaotic opening weeks of 2022, Denis Kireyev, a financier turned HUR intelligence asset, was killed in central Kyiv during an operation run by SBU personnel. Back then, the execution was masked by the fog of an existential invasion. Four years later, a shootout in broad daylight on the left bank of the capital proves that wartime expansion has fostered dangerous institutional rivalries.
The SBU is a leviathan agency boasting tens of thousands of personnel. It handles counterintelligence, counterterrorism, and internal security. Meanwhile, the HUR has evolved from a traditional military reconnaissance wing into an autonomous power player running high-profile sabotage operations, cyber warfare, and foreign assassinations.
Both agencies command vast resources, operate with minimal public oversight, and wield paramilitary muscle. When their operational spheres bleed into one another—such as handling proxy units like the RVC composed of foreign fighters—the lack of a centralized coordination mechanism creates a lethal vacuum. Jurisdictional overlap becomes a zero-sum game of turf.
Fallout and Accountability
President Zelenskyy’s public rebuke was swift, but institutional inertia runs deep. The dismissal of high-ranking security officials, such as Oleg Khramov, head of the SBU department for the protection of state secrets, signals that the political leadership recognizes the gravity of the breach. Yet personnel shuffling does not fix the core architectural flaw.
When intelligence services grow accustomed to operating above traditional legal constraints to fight an external invader, those same habits bleed inward. The line between protecting the state from Russian subversion and guarding institutional fiefdoms against rival domestic agencies begins to blur.
The investigation led by the Prosecutor General's Office and the DBR will likely produce a formal report apportioning blame. It will likely result in procedural adjustments for inter-agency communication. However, the fundamental tension remains unresolved. Kyiv hosts two powerful, heavily armed intelligence bodies answerable to different command verticals, operating within the same cramped geographic theater, and competing for influence in the corridors of power.
The smoke has cleared from Yuriya Shumskoho Street, the traffic has resumed, and the wounded are recovering in hospital beds. But the underlying friction that turned state operatives against each other in the middle of an air raid remains entirely intact.
