A court which was set up to prosecute people for alleged war crimes during the Balkan wars of the 1990s has been described as a “redemptive success” for the United Nations.

Established by the UN Security Council, the International Criminal Tribunal for the former Yugoslavia, or ICTY, was tasked with trying a total of 161 people, mainly Serbs and Bosnian Serbs.

The Guardian newspaper’s Julian Borger has just published a book, called The Butcher’s Trail which tells the story of how many of those people were tracked down.

Daniel Dickinson caught up with him at book event in UN headquarters, and asked him to describe how the tribunal was set up.
