Armenia, Azerbaijan and Russia have signed a deal to end the military conflict over the Nagorno-Karabakh region after about six weeks of bloodshed.

Armenian Prime Minister Nikol Pashinyan, in a Facebook post, described the deal as “unspeakably painful”. He has wished that the deal would become a crucial point in settlement of the issue.

The deal was announced after the Azeri forces had made advancements in many areas including the key city Shusha.

According to the trilateral agreement, Russian peacekeepers would be deployed along the frontline in Nagorno-Karabakh and the corridor between the region and Armenia.

At least 1,000 people have been dead in the conflict that has just ended.

President of Azerbaijan Ilham Aliyev said that the deal was historic as Armenia was forced to come to the table after successes of Azeri forces.

“This statement constitutes Armenia’s capitulation. This statement puts an end to the years-long occupation. This statement is our Glorious Victory!” he wrote on his Twitter.
