Before his trial was suspended indefinitely Thursday due to the prosecution's errors, former Bosnian Serb general Ratko Mladic nodded, smiled and clapped his hands on his lap as 16-year-old footage was shown at his U.N. war crimes tribunal. The film showed the “butcher of Bosnia” screaming at a Dutch general, demanding to know why he authorized NATO planes to bomb advancing Serbian forces. After the footage, Mladic signaled a time-out and the tribunal broke for five minutes. The trial is turning to Mladic’s involvement in a massacre of Muslim men and boys in the Srebrenica region, a U.N. safe haven for Bosnian Muslims who had fled the conflict. The Dutch withdrew when it was clear Bosnian Serb forces were overrunning them, and 8,500 people were killed within a few days.
