Azerbaijan Defence Ministry said that the country’s military had carried out a drone strike operation titled "Revenge" killing two Armenian soldiers in Nagorno-Karabakh, the Jerusalem Post reported on Wednesday.

Tensions between Armenian and Azerbaijani forces have escalated on Wednesday in the disputed region of Nagorno-Karabakh.

Two soldiers of the de-facto Artsakh Republic were killed, and 14 others were injured in Azerbaijani drone strikes in the north-western part of the Nagorno-Karabakh region, the Jerusalem Post cited the Artsakh Defence Army.

The Republic of Artsakh is a breakaway state in the South Caucasus, whose territory is internationally recognised as part of Azerbaijan. In 2020, the predominantly Armenian-populated region of Nagorno-Karabakh where the republic is situated was recaptured by Azerbaijan after a war with Artsakh and Armenian forces.

In the meantime, the Azerbaijani Defence Ministry claimed that Armenian militants fired at Azerbaijani positions in the Lachin district on Wednesday morning, killing one Azerbaijani soldier, the Jerusalem Post said.

Later on Wednesday, the Azerbaijani Defence Ministry announced that it had carried out a drone strike operation titled "Revenge" against a number of groups of Armenian forces in the region.

President of the Artsakh Republic, Arayik Harutyunyan, declared a partial military mobilization in the region, the Jerusalem Post said.

In June, a series of clashes were reported by both Azerbaijani and Armenian authorities near the border between the two countries, the Jerusalem Post added.
