Having earlier vowed to take all necessary measures we shall find out soon enough what Russia has in mind.
The international observers are being held in the eastern city of Slaviansk and are part of a German-led monitoring mission visiting the area under the aegis of the Organization for Security and Cooperation in Europe (OSCE), a Vienna-based body whose 57 member states include Russia.
The group is made up of eight observers, including nationals from Germany Sweden, Denmark, Poland and the Czech Republic, along with several Ukrainian army officers who were accompanying them, the OSCE said.
The separatists invited journalists from Russian media into the building where the observers are being held, and showed military identification cards and military insignia they said were taken from the detainees.
That, the separatists said, was proof that they were not observers but were spying for NATO, according to reports in Russian media. It is standard practice for serving military officers to be seconded to OSCE missions.
