evidence: The contested mountainous region of Nagorno-Karabakh is internationally recognized as part of Azerbaijan, but it has been under de-facto Armenian control since the early 1990s. The landlocked South Caucasus territory declared independence from Azerbaijan in 1991 and, with the support of Armenia, has fought two wars with Azerbaijan in the space of 30 years. The Nagorno-Karabakh region is currently home to an estimated 120,000 ethnic Armenians. [...] Armenian authorities in Nagorno-Karabakh accused Azerbaijan of violating a cease-fire agreement, with Reuters reporting gunfire could be heard in the region's capital on Thursday. Baku has rejected this allegation as "completely false."
