Use of chemical weapons in the Syrian civil war

The United Nations Security Council meets amid concerns of military strikes in Syria by the United States and its allies following a suspected chemical weapons attack in Syria last weekend, with the United States ambassador to the UN, Nikki Haley, accusing Russia of lies and covering for the government of Syrian President Bashar al-Assad, which she said had used chemical weapons at least 50 times in the past seven years of warfare, and the Russian ambassador to the UN, Vassily Nebenzia, blaming the United States, France and the UK for escalating tensions.
