7. The rebels themselves have confirmed that they have chemical weapons.

They released one video announcing that they have them (and showing rabbits being killed by the gasses during trials), and then another pair of videos alluding to chemical suicide bombers who would detonate their chemical weapons as a last defense against government forces if their positions were falling. One of the videos also specifically names a short list of towns with majority Alawite and Christian populations in Latakia that apparently contain chemical weapons stockpiles that will be detonated if Assad's forces try to take them.

The only group claiming that the rebels DON'T have chemical weapons seems to be the American government. Everyone from the UN to the rebels themselves have confirmed that they actually DO.
