Is the ethnic cleansing in europe (balkan region) different from that of central africa (burundi/rwanda)? why

Yes, it is different.

In Europe, the Germans would send the Jews to the concentration camps. The condition for traveling and working in the concentration camps is inhumane. Towards the end of WWII, the Nazi Germany government planned to kill the remaining Jews that were still alive in the camps. Fortunately, they did not successfully execute the plan because the Allied powers blocked the Nazi government's plan and freed the Jews.

In Central Africa, the people who have darker skin are superior than the people who have lighter skin. So the people who have lighter skin goes through harsh treatment from the society and the government. At that time, the government is too corrupted to rule the country so the country is in turmoil. The soldiers tried to execute thousands of people who have lighter skin color. At the end, USA came to save the day by putting a halt to the plan and save a lot of people. Of course, the USA have casualties and difficulties on helping the people.

For the rest, you might want to look it up for a full story at what happen in Central Africa during the ethnic cleansing period.
