Syrian govt. troops feel momentum is in their favor – Frederik Pleitgen reports live from Damascus

The White House is now definitively saying that it is clear that chemical weapons were used in "small amounts" on the Syrian people.

The big question raised now is how forcefully will the White House respond? Frederik Pleitgen is following the developments live in Damascus.

“The big concern here for the Syrian government is of course, or would be, the establishment of a no-fly zone here in this country,” Pleitgen reports.

“Right now, the Syrian government believes it has the momentum on the battlefield. But of course, increased U.S. Involvement could quench that.”
