The Armenian Defense Ministry announced that one soldier was killed and another wounded in an exchange of fire with Azerbaijani troops on the border of the two countries.
For his part, the Azerbaijani Defense Minister said that all illegal activities of the Armenian side should be under constant control.
The Azerbaijani Defense Ministry announced earlier that units of its armed forces took control of a number of highlands, lands and secondary roads in the Lachin region, which connects Armenia with parts of Nagorno-Karabakh, and were under the control of Armenian forces.
Baku accuses Yerevan of seeking to take control of some mines in the Lachin region and using the road to transport weapons and troops.
Armenian Prime Minister Nikol Pashinyan dismissed the Azerbaijani accusations, calling them false propaganda aimed at igniting a new conflict in Karabakh.
Two weeks ago, Pashinyan warned of a "high probability of escalation" at the border with Azerbaijan and in the disputed Karabakh region.
"Today, there is a very high probability of an escalation along the Armenian border and in Nagorno-Karabakh (...) Azerbaijan's rhetoric is becoming more and more hostile," he said, in the context of frequent border clashes since the war between Yerevan and Baku in 2020.
