Situation 2026

Post-2020 war tensions persist along the ceasefire line. Azerbaijan maintains military pressure and has periodically closed the Lachin Corridor (Armenia's only land link to the enclave), creating humanitarian bottlenecks. Sporadic clashes occur; the most significant escalation was a 2023 military operation by Azerbaijan against Armenian forces. Conditions remain volatile with periodic cross-border incidents, though large-scale conflict remains unlikely due to Russian presence.

Background

Nagorno-Karabakh is a mountainous enclave in Azerbaijan with a predominantly ethnic Armenian population. The territory has been disputed since the Soviet Union's collapse in 1991, resulting in a 1994 ceasefire after a devastating war. Armenia controlled the territory for decades. The 2020 war (September-November) saw Azerbaijan, backed by Turkey, recapture significant territory. A Russian-brokered ceasefire established a Russian peacekeeping force (1,960 troops) in the region.

Humanitarian Impact

Approximately 120,000 Armenians remain in Nagorno-Karabakh facing restricted access to medicines, food, and fuel. The Lachin Corridor blockade has caused severe shortages. Internally displaced persons (IDPs) from both communities total over 700,000 regionally. Mental health crisis and PTSD prevalent. Reconstruction needs are significant in war-damaged areas.

Outlook

Tensions likely to remain elevated through 2024-2025. Risk of renewed escalation exists if Russian peacekeeping presence diminishes or geopolitical shifts occur (Ukraine war impacts Russian capacity). Negotiations on final status settlement stalled. Long-term stability depends on international mediation, corridor reopening, and confidence-building measures.
