The Hague tribunal has rejected the argument by former Bosnian Serb leader Radovan Karadzic that he should not be prosecuted because of an immunity deal.

Mr Karadzic said the former US peace envoy Richard Holbrooke had promised him immunity from prosecution if he gave up politics.

Mr Holbrooke has repeatedly denied there was any such deal.

The UN court said even if there was, it did not have legal standing, and that Mr Karadzic's trial should go ahead.

Mr Karadzic, 64, faces 11 charges including genocide.
