Saying the Russians lied is HUGELY speculative. It is very possible and likely the Russians and Turks have some joint operational group to coordinate strikes. It is possible the Turks neglected to update their positions during the fast moving incident and the Russians bombed them. This happens in war quite often. The details vague and unclear. That there is friction in the objectives of Russia and Turkey is not at all a secret. Turkey wanted Assad gone, Russia saved him. DUH!!!
