Jailed Belarusian activist Mikalay Dzyadok faces a new trial, starting on February 25, that could keep him behind bars for another year just as he was due for release.
The trial was to be held inside the prison in the eastern city of Mahileu where Dzyadok, an anarchist, is being held.
Dzyadok's 4 1/2 year prison term on a hooliganism conviction ends on March 3, but he has been charged violating prison rules and could have his term extended by up to one year if found guilty.
Dzyadok says he is innocent.
New York-based Human Rights Watch has recognized Dzyadok as a political prisoner.
