The United States is deeply disturbed by reports that Syria attacked the town of Sarmin using chlorine as a weapon on March 16, Secretary of State John Kerry said in a statement on Thursday.
"We are looking very closely into this matter and considering next steps," he said. "While we cannot yet confirm details, if true, this would be only the latest tragic example of the Assad regime's atrocities against the Syrian people, which the entire international community must condemn."
