 War crimes trials began in 2006, with thirteen people indicted for gender related violence, and for the first time, forced marriage was found by the trial chamber to be a crime against humanity.According to Amnesty International, the use of rape during times of war is not a by-product of conflicts but a planned and deliberate military strategy.Since the end of the 20th century, the majority of conflicts have shifted from wars between nation states to communal and intrastate civil wars.
