Information on the unlawfully detained was from time to time confirmed by the self-proclaimed mayor of Slovyansk, Viacheslav Ponomariov. The unlawful detention of a group of OSCE military observers and their Ukrainian five counterparts came to an end with their release on 3 May, after 10 days in captivity.
