PROSECUTORS at a UN court in The Hague have called for former Bosnian Serb leader Radovan Karadzic to be sentenced to life in prison for his alleged crimes, including the massacre of more than 7,000 men and boys in Srebrenica and the shelling of Sarajevo.

Mr Karadzic was leader of Republika Srpska, an ethnically Serb breakaway state carved out of multi-ethnic Bosnia.

Prosecutors accuse him of having directed a campaign to drive ethnic Croats and Bosnian Muslims out of the country during the three-year Bosnian war, which cost up to 100,000 lives.

Prosecutor Alan Tieger said Mr Karadzic, 69, should be imprisoned for life if found guilty.

His responsibilities included ultimate oversight of the army commanded by Gen Ratko Mladic, who is also on trial for genocide at the UN Yugoslav Tribunal.

Mr Tieger said Karadzic publicly "bragged at the time about the painstaking steps he was taking" to violently remove non-Serbs from parts of Bosnia to create an "ethnically pure" Serb state.
