GENEVA - Three European countries have sought cooperation and information on alleged war crimes committed in Syria's war for use in domestic court cases, a United Nations human rights investigator said on Tuesday. Karen Koning AbuZayd, an American member of the UN commission of inquiry, told a news conference that the Geneva-based investigators had 'already responded to some requests using our database' but gave no specifics. 'Three governments have asked so far,' she later told reporters.
