Armenia and Azerbaijan signed a peace agreement yesterday, ending a decades-long conflict over the Nagorno-Karabakh region that escalated in September (with thousands of soldiers being killed in the last six weeks). The deal was brokered by Russia, which will deploy ~2,000 peacekeepers to the front lines. Under the agreement, Azerbaijan will retain the territory that it secured in the recent fighting and Armenia will withdraw from several adjacent areas in the coming weeks.
More context: The agreement was met with starkly different reactions by the two nations. In Armenia, Prime Minister Nikol Pashinyan called the deal "incredibly painful” and the announcement was met with protests. Meanwhile, the agreement was largely celebrated in Azerbaijan.
