Secretary of State John Kerry said Sunday that samples collected by first responders after the reported August 21 chemical weapons attack in Syria have tested positive for the nerve agent Sarin.
“In the last 24 hours, we have learned through samples that were provided to the United States that have now been tested from first responders in east Damascus and hair samples and blood samples have tested positive for signatures of Sarin,” Kerry said on NBC’s Meet The Press. “So this case is building and this case will build.”
Sarin is a man-made chemical warfare agent considered the most toxic and fast-acting of its kind. The odorless, colorless nerve agent interferes with an enzyme called acetylcholinesterase, which controls nerve signals to the muscles.
