Current Status

Situation 2026

Post-war tensions remain elevated despite the ceasefire agreement. Border skirmishes and artillery exchanges occur intermittently. Azerbaijan consolidates control over reclaimed territories while Armenia faces internal political instability. Disputed demarcation lines and corridor provisions under the ceasefire agreement remain unimplemented. Both sides accuse each other of violations. Russian peacekeepers operate in the Lachin corridor, though their effectiveness has been questioned.

Background

Nagorno-Karabakh is a mountainous region in the South Caucasus with a predominantly Armenian population, claimed by Azerbaijan. The territory has been disputed since the Soviet Union's collapse, resulting in a 1994 ceasefire after a devastating war. Armenia controlled the region for decades until Azerbaijan's 2020 military offensive, which resulted in significant territorial gains and approximately 6,000 deaths. A Russian-brokered ceasefire established a Russian peacekeeping contingent of approximately 1,900 troops.

Humanitarian Impact

Approximately 120,000 Armenians displaced from Nagorno-Karabakh. Limited humanitarian access to remaining Armenian populations. Landmine contamination threatens civilian lives and reconstruction efforts. International organizations report restricted access for monitoring. Shortages of medical supplies and essential goods in Armenian-controlled areas. Missing persons and prisoners of war remain unresolved issues.

Outlook

Risk of renewed military escalation remains moderate if ceasefire mechanisms fail or border demarcation disputes intensify. Long-term stability depends on implementing prisoner exchanges, corridor agreements, and international monitoring. Regional dynamics involving Turkey, Iran, and Russia create uncertainty. Confidence-building measures and lasting settlement prospects remain limited.
