I take your point regarding what type of chemicals they are talking about. I still think any of those countries I mentioned before are all possible culprits for the attack.

I'm so cynical it could be down to anyone. Assad, Russia or America. I'm not in the know about the capabilities of rebels making chemical weapons so I will leave my thoughts to myself. The reason I say America is because if it was them yet Assad/Russia takes the flack from NATO, then it's another nudge, if not the nudge to instigate conflict with Russia.
