There have been reports that Assad's forces have chemical weapons, but Syrian Islamist militants with Jabhat al-Nusra (Nusra Front) were caught in southern Turkey with a cylinder of sarin gas and a load of weapons. They had planned on using the sarin in a bomb which was to be set off in Adana, Turkey.
Twelve suspected terrorists were taken into custody by Turkish anti-terror forces, although five were later released.

That's not to say Bashar al-Assad doesn't also have his dirty hands on some chemical weapons.
There are no heroes in this war.
