Carmel Agius

UN tribunal chief Carmel Agius told a conference entitled 'Stop Genocide and Holocaust Denial' in Sarajevo on Thursday that denial of genocide is unacceptable and those who do it should be prosecuted.

"We must always respond by strongly condemning those who deny it," Agius said.

"It is time to start a big cultural attack. People who deny genocide must be uncovered," he added.

Former Bosnian Serb president Radovan Karadzic has submitted an appeal against the decision not to allow him to appeal his second-instance verdict, sentencing him to life in prison for genocide in Srebrenica, among other crimes.

Mladic, a military leader of Serbs in Bosnia-Herzegovina during the 1992-95 conflict, was previously found guilty on war crimes and genocide charges and sentenced to life in prison - a ruling that both Mladic and the prosecution have appealed against.

UN judges have suspended a court hearing after a war crimes suspect "took poison" when his 20-year sentence was upheld, Sky News reported.

Moments after his conviction appeal was rejected, former Croatian army chief Slobodan Praljak appeared to drink from a small bottle and yelled "I am not a war criminal, I oppose this conviction".
