Hard-line supporters of Serbian mass killer Radovan Karadzic are threatening to bring violent chaos to Belgrade tomorrow with a huge rally in his support.

The woman described by Serbian tabloids as the mistress of Radovan Karadzic denied the claims, saying her world collapsed when she discovered the man she befriended and respected was the war crimes fugitive.

Radovan Karadzic’s lawyer has filed a last-minute appeal against his extradition to the UN war crimes court in the Netherlands, according to a report in Serbia today.
