MOSCOW (Sputnik) — Daesh used chemical weapons in Syria and Iraq, CIA Director John Brennan said.
"We have a number of instances where ISIL [another name for IS] has used chemical munitions on the battlefield," Brennan told CBS News in an interview.
He added that the militant group had capabilities to produce small amounts of mustard gas or chlorine gas and possibly export it to the Western countries.
The CIA chief said that US intelligence was actively involved in searching for chemical weapons or labs producing those in Syria and Iraq.
On Tuesday, US National Intelligence Director James Clapper said an investigation into an alleged Daesh attack in Syria in August revealed that at least two people were exposed to sulfur mustard.
