Kostunica has announced that he will make a request to that end in a letter to UN Secretary-General Ban Ki Moon and that Serbia will try to formulate a proposal to the UN together with other former Yugoslav countries.
"Kostunica's initiative is absolutely unacceptable," Komsic told Dnevni Avaz daily on Saturday, adding that he supported the Hague tribunal's current practice of convict accommodation.
"Kostunica's proposal must not be adopted because in practice it could lead to the use of purely ethnic criteria in the placement of Hague convicts in a prison on former Yugoslav territory," said Silajdzic.
He added that the harmfulness of Kostunica's proposal was evidenced by the recent escape of Radovan Stankovic from a prison in Foca, Bosnia, where he was serving a 20-year sentence for war crimes.
"Serbia does not have the capacities to provide the needed standards and security measures for such a high number of its nationals among Hague convicts," said Silajdzic.
