Yep, Russia will do a thorough investigation for sure. Medvedev came out with some strong words, like an eye for an eye a life for a life stuff. So expect some brutal retaliation when they find out the people behind this.From Intel Slava Z:
"Statements about the alleged involvement of ISIS in the terrorist attack are the same poorly concocted fake news as the previously disseminated fake information. This is part of a disinformation campaign coming from Ukraine aimed at providing information support for the terrorist attack".
I don't know what to believe anymore. I think Daesh is probably behind the attack but Ukrainians could be responsible as well. Probably best to wait for the official statement from the relevant Russian authorities.
Coincidentally, I was thinking of the China eastern airlines crash report that came out few days ago. They ruled out malfunction or defects. But didn’t provide any other details of possible causes. If terrorism was involved, i doubt China would not reveal it though or at least some people would claim responsibility. It’s very strange
