Alternatives could be:
- Assad attacked a facility that had chemical weapons
- the rebels attacked civilians knowing that the US has used those attacks to justify attacking Assad in the past
- as a triple game, the US / Russia drops chemical weapons to justify an attack that would end the "he's a Russian agent" nonsense
The middle being most likely, imo.

Or, the whole thing was staged by the rebels in order to get the US to attack the airbase. It may not have happened at all.
