In breaking news, Syrian activists say gas has been used near the northern Syrian city of Saraqib. Activists told Reuters they suspected the gas was chlorine and that it had affected more than 30 people. The alleged attack took place close to where rebels shot down a Russian helicopter earlier Monday. Syrian government forces have repeatedly been accused of using chemical munitions in the five-year war against rebels seeking to overthrow Syrian President Bashar al-Assad, including during an attack in Damascus in 2013 that killed hundreds.
