Radovan Karadzic is closing his defence saying he takes "moral responsibility" for crimes committed by Bosnian Serbs but denying he ordered killings.

The wartime Bosnian Serb leader set out his case in a written brief before telling the UN tribunal there was not a shred of evidence against him.

He is accused in The Hague of genocide and other crimes, with one charge relating to the Srebrenica massacre.

Prosecutors have called for him to be given a life sentence if convicted.

The 69-year-old political leader of the Bosnian Serbs in the 1990s was handed over to the tribunal when he was arrested in 2008 after 13 years on the run.

More than 7,500 Bosniak (Bosnian Muslim) men and boys, some as young as 12, were killed by Bosnian Serbs in the Srebrenica enclave in July 1995. The massacre is considered Europe's worst since World War Two.

The Balkan conflict emerged from the breakup of the former Yugoslavia, resulting in a bitter inter-ethnic series of wars from 1991 to 1999.

Self-assured

In a written brief that runs to more than 800 pages, Radovan Karadzic argues that he was not aware of the Srebrenica killings but takes responsibility for "any crimes committed by citizens and forces of Republika Srpska (Bosnian Serb republic)".

As he conducted his own defence on Wednesday, he seemed more like a politician outlining his policies than a war crimes suspect facing life in prison, the BBC's Anna Holligan reports.

There was no shaking or stumbling in his delivery, she says. It was the self-assured performance of man who is comfortable in the spotlight.

"It is the Serb people that stand accused," he told his judges. "I know the truth, the prosecution knows the truth, they are trying to delude the court."

UN prosecutor Alan Tieger argued this week that "the policy of ethnic cleansing" had been fully exposed as had "Dr Karadzic as its driving force".

In all, Mr Karadzic faces 11 charges of genocide, war crimes and crimes against humanity.

He has been given 10 hours to speak in court, and will lay out his defence over two days.

The judges are expected to deliver their verdict in a year's time.

During the 1992-1995 war, Bosniaks sought refuge in the town of Srebrenica from the surrounding area as the Bosnian Serb army sought to expel non-Serb populations.

The UN had declared Srebrenica a "safe area" for civilians in 1993 but it fell in July 1995, after more than two years under siege.

Mr Karadzic is accused of orchestrating a campaign of ethnic cleansing together with former Bosnian Serb general Ratko Mladic.

He was arrested in 2008 in Belgrade, where he had spent years masquerading as a faith healer, heavily disguised.

Gen Mladic is being tried separately. Another key suspect, Serbian President Slobodan Milosevic, died in 2006 before the end of his trial.

More than 100,000 people died in the Bosnian war, in which atrocities were committed by all three warring sides.
