A judge has suspended the war crimes trial of Bosnian-Serb wartime general Ratko Mladic on its second day at The Hague.

Media reports cite errors by the prosecution as the reason for the stoppage.

On the first day in the long-awaited war crimes trial Wednesday, the defiant 70-year-old taunted the families of victims.

International prosecutors have indicted Mladic on 11 counts, including genocide, they allege were committed during the early 1990s in Bosnia-Herzegovina.

The prosecution presented video and transcripts of Mladic's phone conversations as evidence of his role in killing civilians during the 43-month siege of Sarajevo.

Mladic is also accused of ordering the massacre of 8,000 Muslim men and boys in the U.N.-protected Srebrenica enclave in July 2005.

Prosecutors say they will use evidence from more than 400 witnesses, though very few of them will testify in court. The first witness is scheduled to appear May 29.

But Mladic is considered a hero by many Serbs, especially in Bosnia. He was arrested a year ago in Serbia, after 16 years on the run as one of Europe's most wanted men. Observers say he could not have been in hiding so long without a support network.
