A view from inside Russia, if you like :-)
The media mentioned (Kommersant) is obviously not the one being read by half-witted fans of Kremlin whose anger could be easily manipulated. It is rather a newspaper for educated white collars who are massively losing their office jobs during the ongoing economical crisis. And Sputnik is nearly unknown (e.g. I just heard about it but unlikely ever browsed). In general, the topic of "Turkish trace" in the A321 tragedy over Sinai is not of big interest here because terrorists have no nationality.
