The appeals trial of four former Serbian state security officers sentenced last year to decades in prison over the 1999 murder of a journalist and outspoken critic of the late strongman Slobodan Milosevic's government began in a Belgrade courtroom on March 6.

The case has been cited as an important event in Balkan efforts to end impunity for crimes stretching back to former regimes. To read the original story by RFE/RL's Balkan Service, click here.
