Armenian armed forces opened fire on Azerbaijani military positions located in the border regions of Kalbajar and Basarkecher early on Sunday, according to Baku’s Defense Ministry.
Armenian forces reportedly fired large-caliber small arms in their intensive shelling of the Azerbaijani army’s positions in the settleements of Yukhar Ayrim, Barmagbin and Zivel.
According to the ministry, adequate measures were taken by Azerbaijani army units in the area.
Relations between the former Soviet republics have been tense since 1991, when the Armenian military occupied Nagorno-Karabakh, also known as Upper Karabakh, a territory internationally recognized as part of Azerbaijan, and seven adjacent regions.
After new clashes erupted in September 2020, Azerbaijan liberated several cities and over 300 settlements and villages that were occupied by Armenia for almost 30 years.
The fighting ended in November 2020 with a deal brokered by Russia.
