It remains to be seen whether the Syrian cooperation will be in full and without any conditions.
There were some problems, but I am optimistic that these problems can be solved, because they will have to be solved, because without this cooperation, we will not have the full picture.
If the investigation is to be completed, it is essential that the government of Syria fully cooperate with the investigating authorities, including by allowing interviews to be held outside Syria and for interviewees not to be accompanied by Syrian officials.
