Investigation Summary
The helicopter was operating a mission to Martuni, a regional center experiencing violent ethnic clashes. On board were several of Azerbaijan's most senior leaders, including Secretary of State Tofig Ismayilov and Public Prosecutor General Ismat Gayibov, who were accompanied by Russian and Kazakhstani peacekeepers intended to monitor the conflict. At approximately 14:42 local time, the helicopter was struck by ground fire. While Azerbaijani investigators later alleged the use of ZSU-23-4 Shilka anti-aircraft guns and SA-6 missiles, the specific heavy weapon systems involved remain a subject of debate, with some accounts suggesting man-portable air-defense systems (MANPADS) or small arms fire. While early TASS reports claimed the pilot had flown into a hill due to poor visibility, the Azerbaijani investigation committee led by Adil Agayev quickly discovered physical evidence of a shootdown. Investigators found holes in the fuselage consistent with a rocket explosion and reported that video equipment and weapons had been looted from the crash site before official recovery teams arrived. The investigation was ultimately curtailed as the crash site fell under the control of Armenian militants, preventing a full forensic analysis or the indictment of specific individuals. The political fallout was catastrophic for regional stability: the Azerbaijani public, viewing the event as a targeted assassination, staged massive protests in Baku that forced the government to abandon peace talks and declare martial law.
Final Conclusions
The investigation concluded that the helicopter was shot down from the ground using large-caliber weapons and likely a surface-to-air missile. Although Armenian officials initially denied involvement or suggested the helicopter was carrying munitions, independent researchers and the Azerbaijani commission identified the cause as a deliberate military strike. The loss of the peacekeeping team effectively ended the ongoing mediation efforts between Armenia and Azerbaijan at that stage of the war.
