Surely this is likely not to be aimed at the airliners. They are collateral damage. The russians have had a lot of aviation assets on the Syrian side of the border. Iran is not far away (and indeed was lobbing missiles at Erbil airport not so long ago) and the Turkey/Kurd situation means that there are any number of big players who might be behind this for primarily military purposes. However I certainly would not fancy flying between the mountains into Sulemanyah right now in the middle of the night in poor weather.
