US Secretary of Defense, Chuck Hagel says Syria’s government has used chemical weapons in its civil war against insurgents. According to Hagel, President Bashar al Assad’s army used sarin, a colorless, odorless liquid, ranked by the United Nations as a chemical weapon owing to its extreme potency as a nerve agent. The US and the UN are conducting an investigation to confirm chemical weapon use in Syria. Last week, Israeli Intelligence analysts issued a report on Assad’s use of chemical weapons.
