Tens of thousands of people have fled Nagorno-Karabakh for Armenia after Azerbaijan launched an offensive to take back full control of the breakaway region.
Nagorno-Karabakh lies within Azerbaijan's borders but for decades has operated autonomously with a de facto government of its own.
The short offensive ended in a Russia-brokered ceasefire in which separatist Armenian fighters agreed to surrender and lay down their arms. Azerbaijan says Karabakh Armenians can remain in the region if they accept Azerbaijani citizenship, but many people have preferred to leave their homes.
The landlocked mountainous region is home to 120,000 ethnic Armenians who make up the majority of the population.
Azerbaijan says it will guarantee the rights of those living in the region. But Armenian Prime Minister Nikol Pashinyan and international experts have repeatedly warned of the risk of ethnic cleansing.
The self-declared republic will cease to exist from next year after its president, Samvel Shahramanyan, signed a decree dissolving state institutions.
