Zagreb - Jewish and Serb activists have attacked the Croatian government for its "political" decision to release second World War concentration camp guard Nada Sakic, who was extradited last year to face war crimes charges. The Simon Wiesenthal Centre said the decision made a mockery of Croatian government claims that it ever had any real intention of providing justice for victims of the second World War ethnic cleansing campaigns in Croatia. Sakic (72) was released from Zagreb county jail on Monday.
