Former Bosnian Serb army commander Ratko Mladic has dismissed the United Nations’ Yugoslav war crimes tribunal as a “satanic court” and refused to appear as a defence witness for his former political master, Radovan Karadzic.

Former Bosnian Serb military chief Ratko Mladic was back in court today for his genocide trial at the Yugoslav war crimes tribunal after recovering from a health scare that saw him rushed to hospital last week.

Ratko Mladic's genocide trial was halted for the second day running because the former Bosnian Serb military commander was still undergoing medical tests after being rushed to hospital yesterday.

Ratko Mladic went on trial at the Yugoslav war crimes tribunal today, 20 years after his troops began ethnically cleansing Bosnian towns and villages of non-Serbs.
