evidence: The Armenian Defense Ministry said the serviceman was killed on May 25 "as a result of a shoot-out that followed the opening of fire by Azerbaijani troops" in Armenia's Gegharkunik district. It said the situation was now "calm" after the skirmish. [...] Earlier this month, Armenia accused Azerbaijani troops of crossing several kilometers into its Syunik and Gegharkunik provinces and trying to stake a claim to territory. Azerbaijan insisted that its troops did not cross into Armenia and simply took up positions on the Azerbaijani side of the frontier that were not accessible in winter months. Nagorno-Karabakh is internationally recognized as part of Azerbaijan but has been controlled by ethnic Armenians since the early 1990s.
