Armenia's Defense Ministry is accusing Azerbaijani forces of shooting dead an Armenian soldier in a border clash.
The Armenian Defense Ministry said the soldier was killed "by the Azerbaijani side" near the northeastern Armenian city of Voskevan on January 17.
Azerbaijan has not commented on the Armenian Defense Ministry's claim.
Armenia and Azerbaijan have been locked in a conflict for decades over the Nagorno-Karabakh region, which both countries claim.
Nagorno-Karabakh is located within Azerbaijan's borders but is inhabited almost entirely by ethnic Armenians.
A 1994 truce ended six years of bitter fighting between the two sides, but both sides frequently claim attacks despite the cease-fire.
