Obama Calls Possible Chemical Attack in Syria "Big Event of Grave Concern"

Hundreds were killed in what opposition activists say was a chemical attack on Wednesday

AUBURN, N.Y. (AP) -- President Barack Obama is calling a possible chemical weapons attack in Syria "big event of grave concern."

Obama says the U.S. is still seeking confirmation that toxic gases were used in Syria. But he says such actions are "very troublesome" and are going to "require America's attention."

However, Obama says the idea the U.S. can solve Syria's civil war is "overstated."
