August 21, 2012(CNN) -- Syrian President Bashar al-Assad should heed U.S. warnings to neither use nor move chemical or biological weapons, lest he risk crossing a "red line" and provoke a U.S. military response, President Barack Obama said Monday.
"We cannot have a situation where chemical or biological weapons are falling into the hands of the wrong people," Obama told reporters at the White House. "We have been very clear to the Assad regime -- but also to other players on the ground -- that a red line for us is we start seeing a whole bunch of chemical weapons moving around or being utilized.
"That would change my calculus; that would change my equation."
"We have communicated in no uncertain terms with every player in the region that that's a red line for us and that there would be enormous consequences if we start seeing movement on the chemical weapons front or the use of chemical weapons."
