(CNN) -- Bosnia genocide suspect Ratko Mladic is back in court Thursday for a procedural hearing, a day after Goran Hadzic -- the last Yugoslav war crimes suspect at large until his arrest last month -- pleaded not guilty to crimes against humanity at the International Criminal Tribunal for the former Yugoslavia.
Mladic, the highest profile Yugoslav war crimes suspect until his capture earlier this year, is accused of responsibility for the killing of nearly 8,000 Bosnian Muslim men and boys at Srebrenica in 1995, the single largest mass slaughter in Europe since World War II.
He has been a combative figure at the ICTY, the United Nations-backed court set up to try war crimes suspects from the wars that followed the dissolution of Yugoslavia in the early 1990s.
The Thursday hearing is a status conference as preparations for his trial continue.
Hadzic, an ex-Croatian Serb rebel leader who had been a fugitive for seven years, was captured in Serbia on July 20.
The former president of a self-proclaimed Serbian republic in Croatia, Hadzic is accused of trying to remove Croats and other non-Serbs from the territory and the "extermination or murder of hundreds of Croat or other non-Serb civilians," among many other crimes, according to the tribunal.
Hadzic had declined to enter a plea at this first appearance on July 25.
He was the last fugitive of the 161 people indicted by the tribunal, which is based in The Hague.
He is charged with a number of offenses committed in eastern Slavonia and Croatia, including persecution, murder, imprisonment, torture, cruel treatment and deportation, the tribunal said.
Prosecutors say he and others sought to permanently remove a majority of the Croat and non-Serb population from about a third of Croatia to make way for a Serb-dominated state.
Hadzic is charged in one incident in which 264 people were taken from a hospital in November 1991, detained and "beaten and tortured before being transported to a remote execution site ... where they were killed and buried in a mass grave," the tribunal said.
Other Croats and non-Serbs were held in "brutal" conditions" characterized by inhumane treatment, overcrowding, starvation, forced labour, inadequate medical care and constant physical and psychological assault, including mock executions, torture, beatings and sexual assault," the tribunal said.
