THE HAGUE (Reuters) - Ratko Mladic was ejected from the courtroom at the UN war crimes tribunal on Monday after the former Bosnian Serb commander heckled the judge when he read out a charge of genocide and entered a not guilty plea on his behalf. Mladic, who appeared in the dock despite earlier threatening to stay away, demanded to appoint his own lawyers and tried to delay entering pleas to 11 charges relating to the 1992-5 Bosnian war. It was his second appearance in The Hague since his capture in Serbia six weeks ago ended 16 years on the run. In a tense hearing that lasted just less than an hour, the 69-year-old former general shouted: "No, no, no Don't read it to me, not a single word," when judge Alphons Orie moved to read the indictment. The judge warned Mladic that he would have him removed from the court if he continued to interrupt. "No, no I'm not going to listen to this without my lawyer," Mladic shouted and removed his translation headphones.
