Jacques Beres, the co-founder of Médecins Sans Frontières, recently returned from Syria. He said that unlike in his previous visits to Homs and Idlib, half the wounded rebel fighters that he treated were non-Syrians. I don't want to suggest that this is necessarily representative of the opposition as a whole. Can you give us some idea of to what extent the Red Cross or other humanitarian groups are finding themselves increasingly treating non-Syrian fighters, and whether this suggests any radicalization within the opposition elements themselves? That's the first question.
Second, is there a need for humanitarian corridors or safe havens to facilitate the delivery of humanitarian and medical assistance, which you said was sometimes difficult and risky, as well as to protect Syrian civilians?
