US Secretary of State John Kerry: What we saw in Syria last week should shock the conscience of the world. It defies any code of morality. Let me be clear: The indiscriminate slaughter of civilians, the killing of women and children and innocent bystanders, by chemical weapons is a moral obscenity. By any standard it is inexcusable, and despite the excuses and equivocations that some have manufactured, it is undeniable.
