Armenia says one of its soldiers has been killed in clashes with troops from neighboring Azerbaijan.
An Armenian Defense Ministry spokeman said the soldier was killed "on the border" late on June 26 and accused Azerbaijani forces of opening fire first.
An Azerbaijani Defense Ministry spokesman denied its forces had started any fighting or lost any of its own men.
Azerbaijan and Armenia have been feuding for decades over Nagorno-Karabakh, an ethnic Armenian enclave in Azerbaijan.
Some 30,000 people were killed in a war over the enclave in the 1990s.
Nagorno-Karabakh has run its own affairs with military and financial backing from Armenia since the war.
Efforts to reach a permanent settlement have failed, despite mediation led by France, Russia, and the United States.
