Nagorno-Karabakh, a mountainous, heavily-forested, landlocked region in the South Caucasus, is at the heart of a decades-long armed standoff between Armenia and Azerbaijan.
On Sunday, the heaviest clashes since 2016 erupted, prompting fears of an all-out war between two former Soviet republics.
Both sides accuse one another of initiating the violence and there are reports of dozens dead.
“We are a step away from a large-scale war,” said Olesya Vartanyan of the International Crisis Group, an NGO focused on preventing and resolving deadly conflict.
She has warned that the current clashes could evolve into a bigger escalation than in April 2016 when dozens of people from both sides were killed in the most serious fighting in the region in years.
