Kerry: US keen not to repeat Iraq experience

US Secretary of State John Kerry has emphatically underlined the evidence America claims points to Assad's regime attacking its own people with chemical weapons on August 21.

He said: "Our intelligence community has carefully reviewed and re-reviewed information regarding this attack, and I will tell you it has done so more than mindful of the Iraq experience - we will not repeat that moment."
