Concerns over Mladic's health dismissed by prosecutors

Ratko Mladic is also held responsible for the siege and bombardment of the Bosnian capital Sarajevo, which killed 10,000 civilians. The prosecution described it as a plan to "spread terror among the civilian population".

In May 2011 he was arrested in a farmhouse in northern Serbia, penniless and in poor health. He recently had an operation for what is believed to have been a hernia, and during pre-trial hearings his attention appeared to wander.

Prosecutor Serge Brammertz has dismissed concerns that Mladic will find it difficult to sit through a 200-hour prosecution case involving testimony from 411 witnesses.
