In a tweet posted Monday evening, U.S. Ambassador to the United Nations Samantha Power said that chemical weapons are devastating Syrian civilians, claiming that Syrian President Bashar Hafez al-Assad is responsible:



The notion prompted quick responses from Power's followers, including Former United States Ambassador to the United Nations and current National Security Adviser Susan Rice:



Power added that a response to the devastation is in the works:



The tweets came hours after Secretary of State John Kerry announced that there was "undeniable" evidence that chemical weapons were being used in Syria.


"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," said Kerry.


Kerry did not, however, directly state that Assad was responsible for the attacks.
