NATO encouraged democracy in Armenia amid growing tension between the military and prime minister.
"We are closely monitoring developments in our partner country Armenia. It’s important to avoid words or actions that could lead to further escalation," NATO spokesperson Oana Lungescu said on Twitter.
"Any political differences should be resolved peacefully & democratically and in line with Armenia’s constitution," she added.
The remarks follow the Armenian military’s demand for Prime Minister Nikol Pashinyan to resign.
Army Chief of General Staff Onik Gasparyan, along with other senior commanders, released a statement Thursday that called for Pashinyan to step down. Pashinyan responded by labeling the demand a coup attempt and urged his supporters to take to the streets to resist.
