When the UN Security Council meets this week to discuss chemical weapons use in Syria, its 15 members should send a strong message to the Syrian government that those responsible for dozens of chemical weapon attacks will be held accountable and may face future prosecution. It should do so first by imposing sanctions on people suspected of involvement in the illegal use of toxic agents, which have killed hundreds of Syrians and seriously injured many more.
By failing to hold those responsible for these appalling crimes accountable, the Security Council has effectively given perpetrators a green light to deploy sarin and other nerve agents, as well as mustard or chlorine gas against men, women and children.
Russia has used its Security Council veto 11 times to shield its allies in Damascus from condemnation, sanctions or referral to the International Criminal Court. Most recently, Russia vetoed renewing a joint investigation of the UN and Organisation for the Prohibition of Chemical Weapons (OPCW), whose job it was to identify the culprits behind chemical attacks.
