Chemical weapons used in Syrian Civil War? Ivan Watson reports

FROM CNN WIRES:

There is a "high probability" that Syria deployed chemical weapons in the ongoing civil war, but final verification is needed, the chairman of the U.S. House Intelligence Committee told CNN on Tuesday.

"I have a high probability to believe that chemical weapons were used," Chairman Mike Rogers (R-Michigan) told CNN's Wolf Blitzer. "We need that final verification, but given everything we know over the last year and a half, I would come to the conclusion that they are either positioned for use, and ready to do that, or in fact have been used."

Rogers' statement comes as the specter of chemical weapons attacks in the Syrian civil war emerged Tuesday, with the government and rebels each blaming the other for using such munitions.

This morning on "Early Start," CNN's Ivan Watson reports on the conflicting accusations of chemical weapons use.
