evidence: Nagorno-Karabakh is a mountainous region internationally recognized as part of Azerbaijan. Roughly 120,000 ethnic Armenians were living there out of the population of a little over 140,000. Under the Soviet Union, which included both Azerbaijan and Armenia, Nagorno-Karabakh became an autonomous region within the republic of Azerbaijan. With the breakup of the Soviet Union, Karabakh declared itself an independent republic. The region came under the control of ethnic Armenian forces backed by the Armenian military in a six-year war that ended in 1994 and killed about 30,000 people. Nagorno-Karabakh became de facto independent, with a self-proclaimed government in Stepanakert, but was heavily reliant on close economic, political and military support from Armenia, according to Global Conflict Tracker. [...] More than 68,000 people fleeing from Nagorno-Karabakh had crossed into Armenia by Thursday morning, according to Armenian authorities. Armenian Prime Minister Nikol Pashinyan accused neighboring Azerbaijan of "ethnic cleansing" and predicted there will be no more Armenians left in the region in the coming days. Pashinyan said in a speech Sunday that his government "will welcome our sisters and brothers of Nagorno-Karabakh to the Republic of Armenia with all care." Armenia's population is about 2.8 million.
