Armenia says that forces from Azerbaijan opened fire on the border between the two countries.
According to the Ministry of Foreign Affairs in Yerevan, a vehicle carrying supplies for Armenian soldiers at the border was fired upon. The shelling has resulted in dead or wounded on the Armenian side, according to the statement.
Azerbaijan denies the data, which has not been confirmed by independent sources.
Armenia accuses Azerbaijan of ethnic cleansing after the Azeri blitzkrieg in the Nagorno-Karabakh region, whose population consists mainly of ethnic Armenians.
Almost all of the disputed region’s roughly 120,000 residents have now fled to Armenia, and the separatist government has announced it will dissolve by the end of the year.
Nagorno-Karabakh is formally within Azerbaijan’s borders, but in practice has been a breakaway region with close ties to Armenia.
