Earlier, Yerevan and Baku agreed to a ceasefire in Nagorno-Karabakh, putting an end to the six-week war in the region.
Mass opposition rallies have erupted in the Armenian capital of Yerevan following the announcement of a ceasefire agreement with Azerbaijan, with protesters demanding the resignation of Prime Minister Nikol Pashinyan, who agreed to sign the deal and withdraw Armenian forces from Nagorno-Karabakh as well as hand over a number of territories to Azerbaijan.
About 10 leaders of the Armenian opposition have since been detained for staging protests amid martial law introduced in wake of the Nagorno-Karabakh flare-up in late September.
The ceasefire deal reached by Yerevan, Baku and Russia on Tuesday resulted in the loss of most territories controlled by the Armenian-majority self-proclaimed Republic of Artsakh, as Azerbaijan and Armenia agreed to stop at their current positions.
The agreement envisages, among other things, the deployment of Russian peacekeepers along the contact line in Nagorno-Karabakh to ensure stability in the region, stop the flow of refugees, and facilitate their return to their places of residence with the assistance of the International Committee of the Red Cross and the relevant UN agencies.
Pashinyan has described the agreement as a very difficult decision for him but said that it was made based on the assessments of people who were most aware of the military situation in Nagorno-Karabakh.
