On the evening of March 24, 1999, student Elena Milincic was at home with her sister and a friend in Belgrade. Suddenly, the quiet evening was interrupted by an air-raid siren. The girls quickly hid under the table. It wasn’t the safest place, but they got lucky – their part of the city wasn’t attacked. Over the next 77 days, these girls and other Belgrade residents got a lot better at hiding from the bombs which threatened to kill them every day. The bombing was part of NATO’s military operation against Yugoslavia – the campaign that shook up the world order, and not just in the Balkans.
