Overview

The 2020 Nagorno-Karabakh war was a six-week armed conflict between Armenia and Azerbaijan over the disputed region of Nagorno-Karabakh and surrounding territories. Hostilities began on September 27, 2020, and ended with a Russian-brokered ceasefire on November 9, 2020, resulting in significant territorial gains for Azerbaijan and widespread allegations of war crimes by both sides.

International organizations, including Human Rights Watch and Amnesty International, documented numerous violations of international humanitarian law. These included deliberate attacks on civilians, use of banned weapons, and destruction of cultural sites. The conflict displaced over 90,000 people and left thousands dead or wounded.

Civilian casualties: At least 170 civilians were killed, including 30 children, during the 44-day war, according to the UN Human Rights Office.
Cluster munitions: Azerbaijani forces fired cluster munitions into Stepanakert and other civilian areas at least 10 times, documented by Human Rights Watch.
Armenian shelling: Armenian forces launched rockets and artillery into Ganja, Mingachevir, and other Azerbaijani cities, killing at least 26 civilians.
Prisoner abuse:Video evidence emerged showing Azerbaijani soldiers executing Armenian prisoners, leading to calls for war crimes investigations.
Cultural destruction: Azerbaijani forces demolished the Ghazanchetsots Cathedral in Shusha and targeted other Armenian religious sites.

Documented War Crimes and Violations

Multiple human rights groups and international bodies reported serious breaches of the laws of war during the 2020 conflict. These incidents involved both state forces and irregular militias, with evidence collected through satellite imagery, witness testimony, and video analysis.

Indiscriminate attacks: Azerbaijani forces used BM-30 Smerch rockets with cluster warheads in populated areas, violating the principle of distinction under international law.
Targeting of civilians: Armenian forces fired Smerch and Tochka-U missiles into Ganja, Azerbaijan’s second-largest city, on October 11 and October 17, killing 26.
Prisoner executions: A video from October 2020 showed Azerbaijani soldiers shooting an Armenian soldier at point-blank range, later confirmed by Amnesty International.
Desecration of bodies:Footage surfaced of Azerbaijani troops mutilating and posing with dead Armenian soldiers, prompting global condemnation.
Forced displacement: After Azerbaijan regained control, over 90,000 ethnic Armenians fled Nagorno-Karabakh, raising concerns about ethnic cleansing.
Use of mercenaries: Armenia accused Turkey of deploying Syrian mercenaries, though Ankara denied direct involvement; UN reports noted foreign fighters in the region.

Comparison at a Glance

Key differences in conduct and impact between Armenian and Azerbaijani forces during the 2020 war:

Violation Type	Armenian Forces	Azerbaijani Forces
Civilian attacks	Fired missiles into Ganja, killing 26	Used cluster munitions in Stepanakert
Prisoner treatment	Some reports of captured soldiers abused	Multiple videos of executions and mutilation
Weapons used	Tochka-U, Smerch missiles	Israeli drones, cluster munitions
Cultural targeting	Limited reports	Destroyed Ghazanchetsots Cathedral
Foreign involvement	Accused Turkey of sending fighters	Used Syrian mercenaries, reportedly

The table highlights asymmetries in tactics and accountability. While both sides committed violations, Azerbaijani forces were more frequently implicated in large-scale civilian harm and desecration. International investigations remain ongoing, but limited cooperation from both governments has hindered prosecutions.

Why It Matters

The 2020 war crimes allegations underscore the fragility of international humanitarian law in regional conflicts. With limited enforcement mechanisms, perpetrators often evade accountability, setting dangerous precedents for future warfare in contested zones.

Accountability gap:No international tribunal has been established, and both Armenia and Azerbaijan have resisted full investigations.
Regional instability: Ongoing tensions increase the risk of another flare-up in 2023–2024, especially after Azerbaijan’s 2023 offensive.
Humanitarian impact:Over 90,000 displaced Armenians face uncertain futures, with limited access to homes and services.
Global precedent: Use of loitering munitions and drones in attacks raises concerns about modern warfare ethics.
Media manipulation: Both sides engaged in disinformation campaigns, complicating truth-seeking efforts.
ICJ involvement: In December 2020, the court ordered Armenia and Azerbaijan to prevent racial discrimination and protect civilians.

Without justice for war crimes, lasting peace remains elusive. The international community continues to call for impartial inquiries, but geopolitical interests often overshadow human rights imperatives.
