On Monday, US President Barack Obama stated that the movement or use of chemical weapons inside Syria would be a "red line" for possible US military involvement in the conflict.
"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," Obama told reporters during a press conference, according to a transcript of his remarks. "That would change my calculus. That would change my equation."
