A United Nations war crimes tribunal is handing down its last judgment, in an appeal by six Bosnian Croat political and military leaders who were convicted in 2013 of persecuting, expelling and murdering Muslims during Bosnia's war.

Wednesday's hearing is the final case to be completed at the groundbreaking International Criminal Tribunal for the former Yugoslavia before it closes its doors next month. The tribunal, which last week convicted former Bosnian Serb military chief Gen. Ratko Mladic of genocide and other crimes, was set up in 1993, while fighting still raged in the former Yugoslavia. It indicted 161 suspects and convicted 90 of them.

The original conviction said that late-Croat President Franjo Tudjman was a key member of a plan to create a Croat mini-state in Bosnia.
