Specifically on Russia, I would have to get back to you. I'm not aware of any specific efforts led by Russia on that specific issue.
With respect to the U.S., it's definitely one of the countries we're working with. I was referring to Minister Dion's participation at the UNGA side event and holding Daesh to account. The U.S. was present there. They're part of a network of countries that are actively looking at these options.
One thing I want to say on accountability is that Iraq has to be a part of it. I'm not talking about Syria, obviously, because it's a completely different business. The solution has to be Iraqi-led. We're working with all of these countries to hopefully come to an accountability mechanism that will work. As I said, so far the focus has been from the Iraqi government. They've really asked for assistance to collect evidence.
The risk is always that with such evidence, if you don't collect it rapidly, there's none to be found by the time you have a tribunal in place to consider the crimes. That's been the focus so far, but certainly there's a lot of work happening as well within the international community to have those discussions about accountability mechanisms.
