"On September 2, between 16:00 p.m. [12:00 GMT] and 16:10 p.m., Azerbaijani armed forces units fired from fire arms towards the Armenian combat outposts nearby Norabak," the ministry said in a statement on Saturday.
Azerbaijan later rejected the accusations, saying that the information shared by the Armenian defense ministry is false.
On Friday, Yerevan stated that four servicemen had been killed as a result of the fire on the border, with Baku reporting its one soldier injured. The Armenian defense ministry later revised the death toll to three people.
Occasional shootouts have been taking place on the Armenian-Azerbaijani border for several years. The two countries are involved in the decades-long conflict over Nagorno-Karabakh, which flared up in September 2020, marking the worst escalation since the 1990s. Hostilities ended with a Russia-brokered trilateral ceasefire declaration signed in November 2020. The two former Soviet states agreed to the deployment of Russian peacekeepers in the region. The latest serious escalation between the two countries took place in September 2022, with both Baku and Yerevan reporting dozens of its soldiers killed.
