John Kerry actually said...
Sarin was used, sarin killed. The world can decide whether it was used by the regime which has used chemical weapons before, the regime which had the rockets and the weapons, or whether the opposition secretly went unnoticed into territory they don't control to fire rockets they don't have containing sarin that they don't possess to kill their own people.
Context
John Kerry emphasizes the use of sarin gas by the Assad regime and challenges the narrative questioning the regime's responsibility for the chemical weapons attack.
