US President Barack Obama has said the use of chemical weapons by Syria would be a “red line” that would change his thinking on intervention in the crisis.
He said he had “at this point not ordered military engagement”.
But he added: “There would be enormous consequences if we start seeing movement on the chemical weapons front or the use of chemical weapons.”
Earlier the new UN special envoy to Syria faced criticism for refusing to say whether President Assad must quit.
President Obama, speaking to reporters at a White House briefing, said the deployment or use of biological weapons would widen the conflict in the region.
