You may wonder what kind of material culture Ṣiluquni (modern Syunik) and partly Urtekhi had in Iron Age ( 1200-500 bc ).
Here are the artefacts from Keren site ( near Kapan ) in Artsakh republic. Today this site is under Azerbaijani control.
Those artefacts are quite distinct. Not similar to anything we had from other parts of Armenia.
It would be interesting to compare them to Khojaly site's. But I have no enough knowledge on this subject.
