I will also support this opinion and supplement it - at that time many Kurds lived in Armenia and Georgia, especially in Tiflis.
I also read that the city of Mosul was famous for its wootz, until the Mongols captured it in the XIII century. Perhaps later the tradition was restored, but I do not know about it.
