Pretty sure this is already blaming Iran itself, there's an implication here that Iran just did this on their own, either on accident or as a false flag.
I would have completely believed that this was ISIS if it wasn't for the immediate flood of perfectly rehearsed western press saying it was definitely ISIS, no doubt. Western media takes longer than that to straighten out the official story when they're legitimately surprised by something. Try harder next time guys.
Well, to be fair, ISIS claims many attacks that aren’t theirs. They literally claimed they did the Vegas shooting, and that was obviously not true, it was an insane white dude with ZERO connections to Isis, it was honestly such a bad lie that Intel officials wrote it off immediately as desperation for attention
