Which was an effect of ethnic cleansing by bosnian serbs in the 1990s?

Many people were killed. Not only Croats and Muslims were killed in the conflict but also Serbs as well.  Eventually, the United Nations peace keepers and United States troops were sent to intervene and stop the Serb’s campaign of ethnic cleansing.  Many Serb officers and officials were arrested and put on trial for war crimes.
