Probably the most pressing country of concern at the moment is Yemen, where we have serious issues of access. We have actually had good news over the past few weeks where we've had some improved access. De facto authorities in Sana'a have actually started to allow us to do better targeting registration, including biometric registration, so we have a better sense that the assistance is getting to the people who are most in need.
When you have these difficult access and conflict countries where monitoring is not always the easiest, you really do need to have a very robust registration system. That has improved over the past few weeks. We had been facing some serious difficulties in that regard.
There's Yemen, where we have had, potentially, pockets of famine. Right behind Yemen has to come South Sudan, parts of northeast Nigeria and then across areas of the Sahel, including Mali, Niger and potentially Burkina Faso. They are, again, very heavily impacted by the climate and conflict paradigm. South Sudan has definitely been in the conflict and climate-related areas.
Those would be the countries of highest concern.
