The destruction of the Armenian khachkars in Old Djulfa in Nakhichevan was unavoidable, Armenian political scientist Levon Melik-Shahnazaryan told PanARMENIAN.Net. "Now we can appeal to all the international structures but we are late. "Barbarism could be prevented in 1919 only when Nakhichevan was a part of Armenia. Presently we cannot but regret over the lost values of the Armenian medieval architecture and art," the Armenian political scientist said.
