Tensions soared again in December when Azerbaijani protesters claiming to be environmental activists blocked the main road between Armenia and Nagorno-Karabakh, leaving its 120,000 residents short of food and other basic supplies.
Azerbaijani soldiers checked vehicles suspected of transporting weapons over the weekend leading to a deadly shootout.
Last month, the United Nations’ highest court ordered Azerbaijan to allow the resumption of free movement along the so-called Lachin corridor, but the situation has remained tense.
On Sunday, Azerbaijan’s Foreign Ministry said a shootout occurred when Azerbaijani soldiers went to check vehicles suspected of transporting weapons along an auxiliary dirt road that links Armenia with Nagorno-Karabakh. Armenia’s Interior Ministry dismissed the claim and described the shooting as an "ambush," saying that three police officers from Nagorno-Karabakh were killed.
The Russian Defense Ministry said on Monday that its troops patrolling the region as peacekeepers under the 2020 Moscow-brokered deal moved quickly to halt the clash. The ministry confirmed that three Nagorno-Karabakh police officers were killed and added that two Azerbaijani troops also died in the shootout.
The Russian Foreign Ministry expressed concern about Sunday's shooting and urged all parties to show restraints and make steps to de-escalate the situation.
