More than 100,000 refugees have now arrived in Armenia from Nagorno-Karabakh, the head of the U.N. refugee agency (UNHCR) said late on Friday.
"Many are hungry, exhausted and need immediate assistance," Filippo Grandi said on social media.
"UNHCR and other humanitarian partners are stepping up their support to the Armenian authorities, but international help is very urgently required," Grandi added.
