US intelligence wanted them weeks ago about an impending attack
Gunmen went in armed, met zero resistance, were busy for over an hour, no police ever showed up.
IS claimed responsibility pretty much immediately.
Putin ignored all that and obviously blamed Ukraine because of course.
This is no false flag operation, Russia would never.
Are you kidding? Almost all terror attacks are one way or another sponsored by counties and governments who are all too happy to see another country suffer.
