"There is no justice or reconciliation until those responsible for this crime are convicted," Jovic said at the inauguration of a monument in Grabovica, north of the southern Bosnian city of Mostar.
He said the aim of the Bosniak authorities in the Neretva 93 operation, when the crime was committed, had been to expel Croats from Herzegovina.
The president of the Croatian association Grabovica '93, Josip Dreznjak, said the crime at Grabovica had been part of a plan for the ethnic cleansing of Bosnian Croats.
The UN war crimes tribunal in The Hague acquitted General Sefer Halilovic of crimes in Grabovica and Uzdol. Two former Bosnian Army members, Enes Sakrak and Mustafa Hota, were each sentenced to 10 years in prison by the Sarajevo Cantonal Court for the killing of a number of civilians.
