Violence erupted in Azerbaijan’s breakaway area in April and led to multiple casualties. The parties signed a Russian-brokered ceasefire in Moscow on April 5 but mutual accusations did not stop.
"Despite the earlier agreement on the ceasefire on the Karabakh contact line, the Armenian side violated the regime 20 times along the line over the past 24 hours," the ministry said in a press release reported by Sputnik.
Nagorno-Karabakh proclaimed its independence in 1991. After the military conflict ended in 1994, Azerbaijan lost the control over the region mostly populated by the Armenians.
