From the Russians came this comment....

Rebels in #Idlib are sitting on a giant stockpile of #Sarin.
No idea where they have it from & why they never used it,but they do.

BUT WAIT.....UN stated the attack was an airborne attack not a ground attack...

This comes from the same ruthless regime that did "not at all" bomb #Aleppo & will never admit,it bombed hospitals after the #IdlibGasAttack
