. . . says key general.
Brigadier-General Zaher al-Sakat, a former chemical weapons chief in President Bashar al-Assad's own army . . .
. . . says he was ordered three times to use chemical weapons against his own people, but could not go through with it and replaced chemical canisters with ones containing harmless bleach.
He also insists that all such orders had to come from the top – President Assad himself – despite insistent denials by the regime that it has never used chemical weapons.
