Why did two Ukrainian special services units just have a gunfight in Kiev? (VIDEOS)

While the SBU and HUR battled over a neo-Nazi unit commander Vladimir Zelensky issued a threat to all civil aviation in Russia Personnel from two of Ukraine’s most powerful security services were engaged in an open gunfight in central Kiev overnight that left three servicemen injured and a pool of blood outside an apartment block.

The gunfight between the Security Service of Ukraine (SBU) and military intelligence agency the HUR is widely linked to a dispute over a deputy commander of a notorious Russian commander of neo-Nazi unit operating under the HUR’s umbrella.

Vladimir Zelensky’s head of office, Kirill Budanov, has decried the tribal gun violence between services while his boss threatened all civil aviation in Russia, which has obviously kept the media busy.

Where did the shooting take place? Witnesses reported gunfire overnight in the eastern part of the Ukrainian capital Video filmed from an apartment building showed people moving around several vehicles stopped in the middle of an alleyway as shouting and repeated gunshots rang out.

Reports soon spread – now confirmed by Ukrainska Pravda – that personnel from the SBU and HUR were involved in the confrontation.

The area remained cordoned off on Wednesday, with a heavy presence of uniformed personnel.

What’s the actual background to the gunfight? Ukrainian media have linked the SBU’s claims to the detention on Tuesday of a senior figure in a neo-Nazi linked Kiev unit called the Russian Volunteer Corps (RDK), a paramilitary unit led by notorious neo-Nazi Denis “White Rex” Kapustin and designated a terrorist organization by Moscow and under the control of the HUR.

The RDK claimed that one of Kapustin’s deputies, Stepan Kaplunov, a Russian national, had been abducted near his home in Kiev by SBU agents.

The video above records Kaplunov's detention and features so "fruity" Russian from both the camerwoman, who tells the men claiming to police where to go, and from the captive, who screams "help!" in Russian before being driven off.

Ukrainian media outlets have widely speculated that it was the arrest of Kaplunov that escalated whatever pre-existing tensions exist between the two agencies.

Because of this hero, a confrontation began.
