( CNN ) -- Bosnian Serb genocide suspect Ratko Mladic is suffering health problems , the International Criminal Tribunal for the former Yugoslavia said Tuesday . The court , however , denied media reports Mladic had collapsed , and refused to comment on reports he had pneumonia . `` Mladic was transferred to the Tribunal with a series of pre-existing medical conditions for which he is receiving treatment . The Tribunal continues to provide Mladic , as any other detainee , with the best possible medical care and attention available in The Netherlands , '' spokeswoman Nerma Jelacic said in a statement . Mladic , wanted in connection with the massacre of nearly 8,000 Muslim men and boys at Srebrenica , Bosnia in 1995 , among other crimes , was captured in May after 15 years in hiding . He is 69 and told the tribunal in June that he was `` gravely ill. '' Prosecutors want to try the former general in two separate cases , they said in August -- once over the Srebrenica massacre and once for spreading terror in the Bosnian capital of Sarajevo and for taking UN personnel hostage . Mladic faces charges of genocide , crimes against humanity , and violations of the laws and customs of war in both cases , prosecutors said in an August 17 statement . Mladic led Bosnia Serb forces in the civil war that broke out in Bosnia-Herzegovina when Yugoslavia dissolved in the early 1990s . More than 200,000 Muslims and Croats died in the 1992-95 civil war in Bosnia-Herzegovina , including nearly 8,000 slaughtered at Srebrenica -- Europe 's worst massacre since World War II . Mladic has been a combative witness at the ICTY . At a July 4 appearance , Mladic refused to enter a plea , demanded new lawyers and repeatedly interrupted the judge until he was removed from the court . The case is now in pre-trial hearings .
Mladic did not collapse , the International Criminal Tribunal for the former Yugoslavia says . He had pre - existing health conditions and is receiving treatment , the tribunal says . He is charged with genocide and other crimes over the massacre at Srebrenica . Nearly 8,000 Muslim men and women were killed there in Europe 's worst massacre since WWII .
