On August 13 , 2004 , a refugee camp in Gatumba was the scene of one of the largest civilian massacres carried out in Burundi in recent years . A force of armed combatants , many of them members of the Forces for National Liberation ( FNL ) , massacred at least 166 Congolese civilians and wounded another 106 . The FNL is a predominantly Hutu rebel movement known for its hostility to Tutsi and the victims were largely Banyamulenge , a group often categorized with Tutsi . The FNL is believed to have been behind a series of other attacks , including the December 28 , 2000 Titanic Express massacre
