"Recently, certain participating States have decided that their respective secondees in the SMM should leave Ukraine within the next days. The SMM will continue to implement its OSCE approved mandate with its monitors deployed in ten cities throughout Ukraine," the mission said in a statement.
An official from the self-proclaimed Donetsk People's Republic said that American, British and Danish SMM employees had left the territory of the republic.
Earlier, CNN, citing informed sources, reported that the US administration intended to withdraw its observers from the OSCE mission.
