Sarin attack in Syria

In 2013, more than a thousand people are thought to have died in a chemical weapons attack on a suburb of the Syrian capital Damascus called Ghouta. It was the single deadliest attack of the Syrian civil war and the UN later confirmed that the nerve agent Sarin had been used. Louise Hidalgo speaks to Angela Kane, the former UN High Representative for Disarmament Affairs. Her team of chemical weapons inspectors reached the site in Ghouta just days after the attack.
