Azerbaijan and Armenia are blaming each other for the latest clash over the disputed region of Nagorno-Karabakh, which reportedly killed five soldiers on Tuesday.
Azerbaijan’s Defence Ministry says the Armenians tried to attack Azeri forces. The government in Yerevan denies that Armenia was at fault.
Three Armenians and two Azeris are said to have died in an exchange of fire on the front line.
Despite attempts to reach a peace deal, tension has continued to simmer in the conflict that began after the collapse of the Soviet Union.
