Azerbaijani military officials are blaming Armenian soldiers for a shooting incident near the border with the breakaway Nagorno-Karabakh region, which is run by an ethnic Armenian administration.
Azerbaijani military officials said Private Nurali Aliyev, 19, was hospitalized in a grave condition after being shot in the head.
Azerbaijan's Defense Ministry accused Armenian servicemen of responsibility, saying they had violated the terms of a cease-fire in the Karabakh area.
The separatist Nagorno-Karabakh Defense Ministry rejected the report, saying "forces deployed along the frontline strictly abide by the cease-fire regime."
Armenia and Azerbaijan have been in conflict for around three decades over the Nagorno-Karabakh territory.
A fragile cease-fire has been in place since 1994 after ethnic Armenians seized control of most of Nagorno-Karabakh.
Years of internationally-backed negotiations have failed to result in a permanent settlement.
