AFP is reporting that an OSCE monitor is missing in eastern Ukraine.
Foreign monitors observing Ukraine's separatist conflict said on Wednesday that one of their local staff has gone missing in the pro-Russian east.
The Organization for Security and Cooperation in Europe (OSCE) said a member of its Special Monitoring Mission (SMM) did not return from a planned vacation on Tuesday and was reportedly being held in the insurgents' de facto capital of Donetsk.
"We are in contact with the relevant actors to resolve this matter," the SMM said in a statement.
"We have demanded his immediate and unconditional release."
