WASHINGTON — President Barack Obama says nobody disputes that chemical weapons were used in Syria. He says that use violates international law and poses, in his words, a "danger to our security."
Obama says the world saw thousands of videos, cellphone pictures and social media posts about the damage inflicted by the chemical weapons attack outside Damascus last month.
He says the U.S. knows that Syrian President Bashar Assad's regime was responsible. He says Assad's forces prepared the attack in the days beforehand. He says they distributed gas masks to their personnel, then fired rockets into neighborhoods the regime was trying to rid of opposition forces.
Obama spoke in an address to the nation Tuesday night from the East Room of the White House.
