U.S. Secretary of State John Kerry has compared Syrian dictator Bashar al-Assad to "Adolf Hitler and Saddam Hussein".
The comments from Kerry came as lab tests proved the sarin nerve agent was used to kill nearly 1,500 civilians.
Kerry told NBC's 'Face the Nation' that Assad has joined the list of Hitler and Hussein, who have used these weapons in time of war, the New York Post reports.
Kerry called the attack an 'affront against the decency and sensibilities of the world'.
