On October 31, 2017, France, President of the UN Security Council for the month, hosted an Open Debate on Children and Armed Conflict (CAC). The October Open Debate followed the publication of the Secretary-General’s 2017 annual report on children and armed conflict. France took the opportunity of the Debate to invite more endorsements and follow-up to the Paris Principles and the Paris Commitments ten years after their launch. The Security Council adopted a Presidential Statement as an outcome document. At the Open Debate, the Council was addressed by the Secretary-General, António Guterres, his Special Representative for CAC, Ms. Virginia Gambia, and Mr. Mubin Shaikh, civil society representative. Seventy-seven delegations representing 100 countries delivered statements, with many reinforcing their support for the Paris Principles, as well as other instruments used to ensure greater protection of children in war, such as the Safe Schools Declaration. A full analysis of the debate and the impact of Watchlist’s advocacy efforts is pending publication, and will subsequently be made available on its website.
