Most unlikely to be true, but an intresting view of what the international community thought of such events. The Belgian abuse of human rights in the Congo cost 10 million lives.
I believe as percentage of population, what the Belgians did in Africa is the worst genocide/massacre in the 20th century (above Holocaust, Pol Pot etc.).
