I happen to know that my colleague, Michael Casasola, was a witness in the other discussion last July on the protection of vulnerable groups and minorities in the OECD, and we can speak about that, too.
In the Great Lakes area, where we see the Burundian refugees, we have no knowledge about this type of problem of ethnic or religious minorities being trepidatious about contacting the UNHCR and to settle in camps where there are other majority groups and there might be tension, but I speak here in general. Sometimes these minority groups don't want to come forward because they don't want to be seen as then being registered as refugees, or in the case of Yazidis, they need to be registered by the host government and they don't want this. It's not so much an issue of the management of UNHCR or its partners which prevents these minorities from coming forward; sometimes it's their own decision, but we can have a whole discussion about this.
What I can say is that we have no knowledge of Burundian minority groups having no access to camps. UNHCR camps should always be accessible to any refugee.
