lol you really should avoid RT, it's little more than Putin's personal video blog.
They'd been blaming everyone under the sun outside of Assad for multiple chemical attacks dating back to near the start of the Arab Spring... heck, Russia blamed three seperate people in succession for the attacks in 2013, saying it was rebels, then someone I've since forgotten, but finishing by claiming the UK gave the chemical weapons to that volunteer white helmet rescue force to use (lol) in order to serve as an excuse for an attack.
Of course, the western world settled that particular issue by signing a deal with Russia and Assad saying there'd be no further use of chemical weapons and that they'd stop producing them/destroy their supply, so those motives seem pretty unlikely given they didn't act on them whatsoever. :p
This "false flag" accusation has been cast about every time they've been used, but if it had been an actual false flag the western powers would have actually capitalized on one of them and invaded by this point. Occam's razor suggests that the local regime, headed by a murderous autocrat which actually possesses all of the chemical weapons that have so far been used and has been linked to their use time after time, may in fact be behind some of these attacks heh
