THE HAGUE (Reuters) - Former Bosnian Serb military chief Ratko Mladic refused on Tuesday to give evidence in support of one-time ally Radovan Karadzic, denouncing the U.N. war crimes tribunal as "satanic" and saying he did not want to incriminate himself.

Mladic, the former general who headed separatist Bosnian Serb forces, and Karadzic, the political leader, are both accused of responsibility for the massacre of 8,000 Muslim men and boys in Srebrenica near the end of Bosnia's 1992-95 war.
