On Saturday, Syrian told the United Nations that it would never use chemical weapons against its peoples and warned that opposition fighters are the ones who could use chemical weapons.
But videos uploaded on the web by activists proved otherwise.
The video showed the destruction caused by what they identified as chemical weapons. They said the fire was caused by a tank dropped from a Syrian warplane and was uncontainable by either water or dirt and was releasing toxic substance as it was bubbling underneath the ground.
In another video, armed opposition captured equipment used as a protection against chemical weapons or gases.
Some media reports said that the substance had been loaded into bombs for warplanes.
British Foreign Secretary William Hague said on Saturday there was evidence the Syrian government could actually employ chemical weapons against the insurgency as an effort to try and contain the conflict which resulted in the death of 42,000 people in nearly 21 months.
