Associated Press reporter Matthew Lee pressed Deputy Spokesperson Toner over American response in Syria during the State Department's press briefing Friday.
"A sarin gas attack could kill a lot of people or it could kill just dozens. But that is a red line. Whereas those dozens of deaths would be a red line if they're caused by a chemical weapons attack. But 40,000 deaths from conventional weapons is not enough to bring international intervention?" Lee asked.
Toner responded that the State Department has "not said what [it] would do, only that it is a red line."
Reports of President Assad readying chemical weapons for attacks against his fellow Syrians have increased this week.
