Azerbaijan and Armenia exchanged prisoners on Monday as part of the peace deal that ended a recent war over the territory of Nagorno-Karabakh.
Tigran Avinyan, Armenia's deputy prime minister, announced that 44 captives had been returned to the country from Azerbaijan.
Meanwhile, 12 captives were handed over to Azerbaijan, the Russian Defense Ministry confirmed.
The exchange was facilitated by Russian peacekeepers that have been deployed to the region under the deal, which was brokered by Moscow.
It wasn’t immediately clear how many more prisoners the two countries intend to exchange.
Armenia and Azerbaijan fought a bloody war over Nagorno-Karabakh in the early 1990s which ended in a truce although sporadic episodes of violence have since taken place.
