A U.N. tribunal convicted two Serb cousins Monday of having burned alive more than 100 Muslims in what the presiding judge called a part of the "wretched history of man’s inhumanity to man." Milan Lukic and Sredoje Lukic were convicted of crimes dating back to the early 1990s, during the bitter ethnic conflict that ravaged the former Yugoslavia. The crimes include two incidents in which Muslim men, women and children were forced into homes that were then set on fire — some who tried to escape were shot.
