The response is multi-faceted. First of all, let me perhaps break it up into three parts. First are the investigative mechanisms, and there Canada is contributing, for example, to the Commission for International Justice and Accountability for the fact gathering and evidence gathering.
There is the support to the victims, including victims of sexual violence, and there Canada is also active.
As to the mechanisms themselves, the legal mechanisms, whether it's the ICC, ad hoc tribunals, or other mechanisms, the international community is indeed struggling given the complexity of the conflict, the many actors, and the politics that play out in the various bodies for action to be taken, but Canada is certainly pressing.
Minister Dion earlier this year wrote to the UN Security Council to ask for action to be taken and an investigation of the crimes of Daesh.
