Some of the worst war crimes happened in Kosovo.
Kosovo was part of Serbia but the biggest group living there were Albanians. (Albania is next to Yugoslavia.)
It's said Milosevic wanted them out to make room for the Serbs. Tens of thousands of people died and their bodies have been found in huge graves in the area.
Yugoslavia was now in a bad way. The rest of the world was shocked by the terrible killings and torture in Kosovo, and brought in lots more sanctions. But Milosevic still tried to bounce back and promised to rebuild the nation.
