The Organization for Security and Co-operation in Europe says it is extremely concerned about the detention of several Ukrainian members of its monitoring mission in the east of the country.
The Vienna-based body said in a brief statement Sunday that it is "using all available channels to facilitate their release." A spokesperson declined to specify how many national mission members were detained, when or by whom.
Several OSCE observers have been killed or injured since the body's 57 participating states established a mission to monitor the conflict in eastern Ukraine eight years ago. Russia recently vetoed an extension of the mission.
