The Armenian side has not assumed any unilateral obligations to clarify the fate of the missing, Armenian Foreign Ministry spokesman Vahan Hunanyan told Radio Azatutyun.

"Both in the first and the second Artsakh war, the Armenian side has missing persons. We attach importance to finding out the fate of the missing. In this sense, the Armenian side did not assume any unilateral obligations," he said.

After returning eight Armenian prisoners of war, Azerbaijan said that in exchange it expects to receive information about the Azerbaijani soldiers and civilians killed in the first Karabakh war and presumably buried in mass graves, as well as the location of these graves.
