Breakaway Nagorno-Karabakh said one Azeri soldier was killed on Saturday in fighting on the frontlines of the Armenian-backed rebel region, the second reported clash in days.
Skirmishes are common near the mountain region, where Armenia-backed Christian ethnic rebels attacked Azerbaijan-ruled region with the support of Armenia in fighting that erupted as the Soviet Union headed towards its 1991 collapse.
The Nagorno-Karabakh army said in a statement it had "repelled" an assault by an Azeri "sabotage" unit at the northeastern section of the front-line on Saturday morning.
"As a result of the measures taken by the Karabakh side ... the Azeris were driven back, leaving one body ..." it said, adding that no Armenians were killed.
Private Azeri television ANS, without citing a source, reported two Azeri army officers killed and a third soldier wounded. The two sides frequently offer different casualty figures and conflicting accounts of skirmishes.
On Tuesday, Azerbaijan said two of its soldiers and three Armenians had died. Armenian-backed forces in Nagorno-Karabakh denied suffering any losses in that clash.
Speaking the next day, Azeri President Ilham Aliyev promised his country's flag would again fly over Nagorno-Karabakh.
