Former Bosnian Serb army chief Ratko Mladic goes on trial this week in a case that will establish if he was responsible for some of the worst atrocities in Europe since Second World War.

The former chief of the Yugoslav army has been jailed for 27 years for aiding Bosnian Serb forces responsible for the Srebrenica massacre and deadly four-year campaign of shelling and sniping in Sarajevo.
