Continuing with armed provocations, Armenian forces on Monday fired upon Azerbaijani army positions in two different locations on Monday, the latter's Defense Ministry said.

Armenian military positions in Vedi city opened fire on Azerbaijani positions in Nakhchivan's Heydarabad village in Sadarak city, and Kalbajar’s Yukhari Ayrim village during afternoon hours, a statement said.

The Azerbaijani army, which responded with retaliatory fire, reported no casualties, it added.

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.

New clashes erupted last September and ended on Nov. 10 with a Russia-brokered cease-fire.

During the 44-day conflict, Azerbaijan liberated several cities and nearly 300 settlements and villages from Armenia’s nearly three-decade occupation.
