VIENNA: The world’s largest security body said on Sunday it is “extremely concerned” after several of its Ukrainian members were believed to have been arrested in pro-Russian separatist territories in the country’s east.

The Organisation for Security and Cooperation in Europe (OSCE) evacuated many of its staff from the country after Russia’s invasion of Ukraine on Feb 24.

Many had been in the east to observe a ceasefire after Russia’s 2014 annexation of the Crimean peninsula.

Several Ukrainian members stayed, and the OSCE said on Twitter they had been “deprived of their liberty”, in line with Russian media reports they had been arrested.

“The OSCE is extremely concerned that a number of @OSCE_SMM national mission members have been deprived of their liberty in Donetsk and Lugansk,” it said in a tweet on Sunday.

It added that it is “using all available channels to facilitate their release”.

The security services of the Lugansk separatists said this month they had arrested two members of the OSCE mission, according to Russia’s TASS news agency.

TASS said one of them had “confessed” to passing “confidential military information to representatives of foreign special services” and that a high treason investigation had been opened against him.

The Donetsk separatist prosecutor’s office confirmed he had opened espionage probes against several OSCE employees suspected of having collected and transmitted “information constituting state secrets” to the Ukrainian secret services.

The prosecutor’s office said this included videos revealing the position of separatist military units. On Sunday, the US ambassador to the OSCE, Michael Carpenter, called for the body’s members to be released.
