According to the Associated Press, the bus entered Armenia carried 15 passengers with serious illnesses and mobility problemssaid Kayam Stepanian, human rights ombudsman of Nagorno-Karabakh.

Within 24 hours, Azerbaijan managed to take control of the region after a military intervention launched and forced the separatist forces of Nagorno-Karabakh to capitulate.

While Baku is committed to respecting the rights of Armenians in Nagorno-Karabakh, most left the area immediately, fearing reprisals or restrictions on their language, religion and customs.

The Armenian government said on Monday that 100,514 of the 120,000 inhabitants of the area they are estimated to have crossed into Armenia.

Armenia’s health minister, Anahit Avanesyan, said some died during the grueling and slow journey through the mountain corridor to Armenia that took up to 40 hours. It was preceded by a nine-month blockade of the region by Azerbaijan that left many suffering from malnutrition and a lack of medicine.

Sergey Astsetryan, 40, one of the last residents of Nagorno-Karabakh to leave the region in his own vehicle on Sunday, said some elderly people have decided to stay, adding that others may return if they see it is safe for Armenians to live under the rule of Azerbaijan.
