On March 24, 1999, the North Atlantic Treaty Organization starts their air bombardment campaign on Yugoslavia, making it the first time in history that NATO has attacked a sovereign country.
Yugoslav forces and Albanian militants continue to battle as a large portion of the population of Kosovo is displaced. It’s said that close to 1 million people are forced to move.
A large scale campaign of ethnic cleansing (which is known as Operation Horseshoe) was the reason that the NATO intervention originally took place. During later trials it was confirmed that many Yugoslav security forces were responsible for “crimes against humanity.”
