The U.N. War Crimes Tribunal has officially transferred a case against two former Croatian generals back to Croatia.

The Hague court indicted Generals Rahim Ademi and Mirko Norac for crimes against humanity for the September 1993 attack on ethnic Serbs in the Medak Pocket in central Croatia.

The two were allegedly behind a military operation that included stabbing, beating, and torturing Serb civilians.

This the first case to be sent back to Croatian courts by the tribunal.

The tribunal is referring so-called lesser cases to Croatia, Serbia, and Bosnia-Herzegovina to lighten its load of Balkan war cases.
