John Schinder has written this article 'Who Really Murdered 224 Innocent People on Flight 9268?' and the sub-title says it all almost:
First Moscow said the Islamic State brought down their jetliner—now the Kremlin claims it was Turkish nationalists

The very short version: the last two paragraphs:
Moscow’s revised propaganda is consistent with presenting Ankara as the “real” force behind ISIS, which is a now-standard trope in Russian media. “Low-grade Kremlin bull####” was how a senior American intelligence official with extensive experience in the region described the current Moscow line on the Grey Wolves: “trying to pin the airline disaster on Ankara this way is sure to kick the hornet’s nest in Turkey.”

That the Grey Wolves, not the Islamic State, murdered 224 innocent people is a far-reaching claim that requires genuine evidence to be taken seriously. To date, none has been forthcoming. If Moscow has such evidence, it needs to present it to the world, before the rising tensions it’s creating with Turkey threaten to engulf an already dangerously unstable region.
