President Barack Obama says a possible chemical
weapons attack in Syria this week is a "big event of grave concern" that
has hastened the timeframe for determining a U.S. response.However, Obama said the notion that the U.S. alone can end Syria's bloody civil war is "overstated" and made clear he would seek international support before taking large-scale action.
"If the U.S. goes in and attacks another country without a U.N. mandate and without clear evidence that can be presented, then there are questions in terms of whether international law supports it, do we have the coalition to make it work," Obama said during an interview with CNN. "Those are considerations that we have to take into account."
