I’m not too sure about that...but even assuming that this is correct...who, EXACTLY, claimed this? How do we KNOW it was ISIS that claimed it, vs. someone claiming to be speaking for ISIS.
My point is only that we should wait for the facts to become more established before assuming that any of them are true (other than that there was a mass shooting, and that 50 or so are dead, with 400 or so wounded - THAT is pretty well established at this point).
Looks like it came from ISIS’s “news agency” — and senior US officials are saying they were unaware of any such connection:

Oh, and fog of war skepticism is fair. But just even the Indonesian girlfriend there who has traveled to the Middle East makes this very suspicious IMO.
