Thank you for that question. It's a very important one.
Establishing a fact-finding mission or commission of inquiry obviously has to be done through multilateral forums, either through the United Nations or through the African Union, and in coordination with states that can apply pressure on the current government to allow for access to the impacted regions in particular, and also for there to be ensured security for those investigators in the process.
Without a multilateral, independent commission, I don't think it would be possible, as you note, given the instability in the region and the current state of denial, frankly, by the current government with regard to what's going on.
