My understanding, correct me if I'm wrong, is that Doctors without Borders still has staff in the region and I assume we'll know more about the work of Medecin du Monde from the interview with one of their directors this weekend. I included the links in my comment further up.

Clearly European NGOs have been involved and the EU representative in Sudan was briefing reporters on the status of Peace negotiations so the EU is there in some capacity. The question is politically and militarily should the EU be more actively involved and if so how? What is the current policy?
