April chemical attack in Syria was perpetrated by Assad regime: UN

In a report issued on Wednesday, the UN said Syria has used chemical weapons against its own people in rebel-held areas nearly 30 times since the country's civil war began in 2011, including the April attack that left almost 90 people dead and hundreds of others wounded. The report by the UN Commission of Inquiry on Syria said the "gravest incident" was the April 4 attack in which the Syrian air force dropped sarin bombs on the town of Khan Sheikhoun. Several days after the chemical attack, the US retaliated by firing 59 Tomahawk missiles at a Syrian airbase. Out of the 33 chemical attacks documented until now, 27 were perpetrated by the Syrian regime, the UN report said. The commission has yet to determine who was responsible for the six others.
