Disputes over the ownership of Nagorno-Karabakh eventually escalated into a large-scale military conflict, where Armenian forces occupied of most of former NKAO and seven adjacent districts. According to HRW, systematic abuse of human rights was carried out by Karabakh Armenian forces and by the governments of Azerbaijan and Armenia. A cease-fire was achieved in 1994 and still remains in effect as the Nagorno-Karabakh Republic is "de facto" independent, while "de jure" inside Azerbaijan's borders. The unresolved conflict with Armenia over Nagorno-Karabakh as well as the presence of up to 880,000 refugees and IDPs in Azerbaijan contributed significantly to aggravating the economic, social and political situation in Azerbaijan, with around 14% of the country's territory occupied by Armenian forces.
