Syria: 'Bashar al-Assad ordered me to gas people - but I could not do it' - Telegraph
Gen Sakat said the regime wanted to "annihilate" the opposition using any means, and said he received his first orders to use chemical weapons in October last year. On three occasions, he said he was told to use a mixture of phosgene and two other chlorine-based agents against civilian targets in Sheikh Masqeen, Herak, and Busra, all rebel-held districts.
However, under cover of darkness, he said he had replaced the canisters containing the chemicals with ones containing water mixed with dilute bleach which would give off a similar chlorine smell.
At first, his trick worked. "They were completely convinced that this was the same poisonous material," he told the Sunday Telegraph in an interview. "In this way I saved hundreds of lives of children and others."
But after the third occasion, in January, his bosses became suspicious at the lack of deaths in his "attacks" and he began to plot his escape to Jordan, where he has been based since the spring.
