They carried banners accusing Karadzic of genocide.

Some carried pictures of the thousands of people who went missing during the Bosnia War.

Some of  the charges against Karadzic stem from the 43-month siege of Sarajevo that began in 1992.
   
An estimated 10,000 people died in the siege as the former Yugoslavia was torn apart by Serbs, Croats and Muslims fighting for land.
   
Karadzic is also charged with the killing of more than 7,000 men and boys in Srebrenica.
 
He faces nine other counts of murder, extermination persecution and forced deportation.
 
At the start of the trial, last October, prosecutors vowed to prove that Karadzic led agenocidal campaign to make Bosnian Muslims "disappear from the face of the earth."
     
They contend he wanted to carve out a mono-ethnic state for Bosnian Serbs, during the war that killed an estimated 100,000 people.
