Initial observations suggest sarin was used by government forces, but further investigation is needed

A suspected chemical attack on a rebel-held town in Syria has triggered the first direct US military action against the country’s government forces as the US launched a missile strike against a Syrian air base earlier today. Following the attack on 4 April, there were reports of residents dying in their houses, with victims and injured survivors showing symptoms that match poisoning by nerve agents. However, there is no evidence yet to identify which one.
