Prosecutors are calling for former Bosnian Serb leader Radovan Karadzic to receive a life sentence for his role in the 1995 Srebrenica massacre.
Karadzic is on trial in the Hague for eleven crimes including genocide, accused of directing a campaign against other ethnic groups during the Bosnian War.
He denies the charges.
Over 8,000 men and boys were murdered at Srebrenica, described as the worst crime on European soil since the Second World War.
“Under his command and oversight, Karadzic’s subordinates and those cooperating with them expelled, killed, tortured and otherwise mistreated hundreds of thousands of Muslims and Croats,” prosecutors wrote in a brief published on Friday.
100,000 lives were lost altogether during the three-year conflict.
Prosecutors will start their closing statements to the court on Monday and Karadzic, who is defending himself, will respond on Wednesday.
Judges will then retire to decide on a verdict and a sentence.
