The conflict ended when Russia, which has a military base in Armenia, signed a peace treaty and sent nearly 2,000 peacekeepers to the region. Turkey sided with Azerbaijan, which regained the land it had lost in a previous conflict.
“Under the agreement brokered by the Russian side, the fire ended on the eastern part of the Armenian-Azerbaijani border and the situation is relatively stable,” the Armenian Ministry of Defense said.
The Azerbaijani Ministry of Defense did not immediately respond to Reuters’ request for comment.
Earlier on Tuesday, Russian President Vladimir Putin and Armenian Prime Minister Nikol Pashinjan discussed the border situation over the phone, the Kremlin said.
Russian Defense Minister Sergei Shoigu also spoke by telephone with the Armenian and Azerbaijani defense ministers, Interfax news agency reported.
The Armenian Ministry of Defense said its troops had been fired from Azerbaijan and 12 of its soldiers were imprisoned, while two combat stations near the Azerbaijani border were lost.
Eduard Aghajanian, head of Armenia’s parliamentary foreign affairs committee, said 15 Armenian soldiers had died.
The Azeri Ministry of Defense said it had responded to large-scale “provocations” after Armenian forces bombed Azerbaijani army stations and that its own operation had been successful.
The French Foreign Ministry had expressed its deep concern at the deteriorating situation and called on both countries to observe a ceasefire.
