On Saturday, Armenia began its three days of mourning for Nagorno-Karabakh war victims according to AFP.
More than 5,000 people including civilians were killed from both sides during the flamed war between both states
After the war ended in November, both states signed a peace agreement pushed by Russia. Also, Armenia had to surrender controlling many regions in Nagorno-Karabakh to Azerbaijan.
The deal caused huge local opposition in the Armenian state urging Prime Minister Nikol Pashinyan to resign.
Pashinyan supposed to lead a procession to a memorial complex in the capital Yerevan where war victims were buried on Saturday.
On the other hand, the opposition is planning to hold a separate march later on Saturday.
"The entire nation has been through and is going through a nightmare," Pashinyan said in a video address ahead of the memorial march.
"Sometimes it seems that all of our dreams have been dashed and our optimism destroyed," he added.
