Death toll: over 400, 000 people
One of the most recent countries in the world that caused lots of casualties is Sudan, according to recent dates. From 2003 until 2010 there was a war between rebel groups and government in Sudan. As a consequence, there was a major ethnic cleansing of civilians (approximately 480, 000), and indictment of Sudan’s President Omar al-Bashir by International Criminal Court for genocide, war crimes and crimes against humanity.
