The health of Serbia’s ultranationalist former deputy Prime Minister has deteriorated while in custody in the Netherlands. Serbia has asked the United Nations War Crimes Tribunal in The Hague to transfer Vojislav Seselj to a hospital in Belgrade for treatment. There has been no reponse from tribunal officials. Tests show Seselj, who is on hunger strike, has lost 25 kilos and doctors say his condition is giving cause for concern. Selselj surrendered to The Hague tribunal in 2003 but pleaded not guilty to charges of war crimes dating from the 1990s. The hearing was adjourned indefinitely on Friday.
