US Planning Military Response to Alleged Chemical Use in Syria

A quick one

The U.S. government is stepping up its involvement in the Syrian crisis after allegations of chemical weapons use -- with its top military official making plans to respond quickly, and its top diplomat reaching out to Syria's foreign minister and others in the wake of the report.

On Saturday, a senior State Department official said that Secretary of State John Kerry had talked Thursday -- the day after the attack -- with Syrian Foreign Minister Walid Moallem.
