The Azerbaijani Defense Ministry denied the allegations that it fired cross-border shots at Armenian positions.

Armenia stated that one of its soldiers was killed in a border gun battle with Azerbaijani forces. Tensions remained high after the war against the disputed Nagorno-Karabakh region last September.

The Armenian Ministry of Defense said on Tuesday that the gun battle took place on its eastern border with Azerbaijan.

It later stated that the situation was “calm” after a skirmish at the Verin Shorzha border point in the Gegharkunik region of eastern Armenia.

The Ministry of National Defense said in a statement: “A soldier was killed as a result of a gun battle after the Azerbaijani army opened fire.”

Late on Tuesday, the Azerbaijani Defense Ministry denied Armenia’s allegations that it opened fire across the border at Armenian positions.

The Ministry of Foreign Affairs of Azerbaijan said in a statement: “According to our information, the incident involving the death of an Armenian soldier was an accident and has nothing to do with Azerbaijan.”

A long-lasting Nagorno-Karabakh conflict broke out into a full-scale war in late September, killing approximately 6,000 people in the six-week fighting.

After driving Armenians out of their controlled territory in and around the Nagorno-Karabakh region since the 1990s, Russia helped ensure a ceasefire in November.

Russia has a military base in Armenia and last year sent peacekeepers to the area to help implement the ceasefire.

It has strong ties and mutual defense treaties with Armenia, but it is also very friendly with Azerbaijan.

The ceasefire was basically maintained under the supervision of approximately 2,000 Russian peacekeepers, but tensions continued and several border incidents occurred.

Earlier this month, Armenia accused the Azerbaijani military of “infiltrating” across the southern border and “siege” a lake shared by the two countries.
