The UN court on Wednesday upheld the sentences of Jadranko Prlić (left), Bruno Stojić (center left) and Slobodan Praljak (center) before Praljak drank what he claimed was poison, and later died. Milivoj Petković (center right), Valentin Čorić (right) and Berislav Pušić (not pictured) also had their existing convictions upheld.

The generals were involved in directing the Croatian Defense Council (HVO), the Bosnian Croat army that carried out ethnic cleansing in eight areas in central and southern Bosnia: Čapljina, Gornji Vakuf, Jablanica, Ljubuški, Mostar, Prozor, Stolac and Vareš. Many victims were Muslim Bosniaks, but the HVO also targeted other non-Croat ethnic groups.

HVO forces attacked the city of Mostar in 1993. They destroyed the city's Mosque and killed multiple Bosniak army prisoners, mainly via savage beatings. Slobodan Praljak, who was the HVO's leading commander, also ordered the destruction of the city's 16th-century Ottoman bridge known as "Stari Most" ("Old Bridge"). The renowned bridge was rebuilt 11 years later.

HVO forces pillaged and destroyed several villages in the Gornji Vakuf in early 1993. In many cases, HVO soldiers set fire to homes of Muslim Bosniaks. According to the verdict in The Hague, Jadranko Prlić, Bruno Stojić, Slobodan Praljak, Milivoj Petković and Valentin Čorić helped organize and carry out the military operations in Gornji.

The villages of Sovići and Doljani in the scenic area of Jablanica came under heavy Croat shelling in April 1993. After entering the villages, HVO soldiers killed four Bosniak army detainees and abused multiple women and children. In its 2013 verdict, The Hague court determined that Milivoj Petković had also been responsible for blocking international observers from entering Sovići and Doljani.

The six generals were also involved in HVO attacks on a dozen villages in Prozor, including Parcani, Podaniš, Lizoperci, Lug, Skrobućani and Tošćanica. Croat forces burned Bosniak homes, destroyed their property and killed multiple men and women. In one instance, they "violently abused" between 400 and 500 Bosniak soldiers in a local secondary school. Some detainees were sexually abused.

The Lokve and Višići mosques were destroyed in the Čapljina municipality in the summer of 1993 after HVO soldiers began forcibly evicting Bosniak civilians from the area. During the operation, two women and an elderly disabled man were shot and killed. A few days later, Croat forces executed 12 Bosniak men before burning their bodies outside of the village of Bivolje Brdo.
