State Department: We have proof Syria was behind gas attack

The U.S. State Department said Friday that it has proof that Syria was behind the alleged gas attack that left more than 40 civilians dead in Douma last week. Heather Nauert, a department spokesperson, said officials are still trying to determine what kind of chemical was used in the attack. 

She said there was a “very high-level of confidence” that Syria was behind the attack.

“We believe we know who was responsible for this. We will still wait — the Organisation for the Prohibition of Chemical Weapons (OPCW) will still formulate its facts and its findings, but it does not determine the responsibility, they determine the substance,” Nauert said Friday. 

This is a developing story and will be updated.
