Armenian police detained 88 people at a protest in the capital Yerevan by demonstrators demanding the resignation of Prime Minister Nikol Pashinyan over his decision to cede several border villages to Azerbaijan.
Armenia said last month it would return the uninhabited villages in what both sides said was an important milestone as they edge towards a peace deal after fighting two wars since the collapse of the Soviet Union.
