WASHINGTON — The U.S. envoy to the United Nations says Syrian President Bashar Assad "has barely put a dent in his enormous stockpile" of chemical weapons that American officials believe killed more than 1,400 people outside Damascus last month.
Ambassador Samantha Power says the world has done very little to curb Assad's willingness to use the deadly nerve agents again.
Power also said Friday the United States has exhausted all alternatives short using of military force to deter Assad from using chemical weapons on his own people in the future.
Power was speaking at the liberal-leaning Center for American Progress think-tank in Washington.
She again accused Russia of blocking a U.N. Security Council vote to take action in Syria.
