SARAJEVO, Bosnia-Herzegovina—Bosnia's top war crimes court has jailed a former Bosnian Serb policeman for 20 years after judges found he took part in the 1995 Srebrenica executions—the worst massacre in Europe since World War II, in which over 8,000 Muslim Bosniak men were killed.

After the eastern Bosnian town fell, prosecutors told the court Bozidar Kuvelja, now 42, searched houses for Muslims to take to a collection point where men were separated from women for execution. He also was found to have taken part in the killing of several hundred of them and even finished off with a pistol those in the pile who showed signs of life.

The prosecution said it would appeal the sentence, saying 20 years is not enough.
