A highly unusual gunfight between allied forces erupted on the streets of Kyiv, the Ukrainian capital, on September 2nd, with the nation's two primary military intelligence bodies—the Security Service of Ukraine (SBU) and the Defence Intelligence of Ukraine (HUR)—engaging in an exchange of fire.

According to Ukrainian media reports, preliminary investigations suggest the confrontation stemmed from a grave case of mistaken identity, as operatives from both agencies allegedly misidentified each other as Russian infiltrators, triggering what has been described as an "internal spy war."

The brief but intense clash left three HUR operatives wounded in the aftermath of the incident.
