In a statement carried by Banja Luka's Nezavisne Novine of Monday, Mihaljevic said that UN war crimes tribunal chief prosecutor Carla del Ponte would be given "some of the documents" that she had requested.
Mihaljevic would not give any details about the documents nor about where they had been located.
Although the paper does not quote the official, it claims that Mihaljevic spent last week in Zagreb searching for the documents at the Croatian National Archive.
The same source says that there are indications that the former director of the recently dissolved Intelligence-Security Service (FOSS) of the Croat-Muslim federation, Ivan Vuksic, had previously sent to Zagreb a truck-load of documents relating to Herceg-Bosna.
Mihaljevic only said that he had looked for the documents at places where he believed he could find them.
Dissatisfied with the slow response to her request from July, del Ponte on 31 August again wrote to the highest Bosnian officials setting 30 September as the final deadline for the submission of all available war documents of Herceg-Bosna, the Sarajevo-based Dnevni Avaz daily reported today.
Last week a similar request was forwarded to the Bosnian Serb authorities in Banja Luka to immediately submit to the office of the chief prosecutor the war-time archives of the Bosnian Serb army.
Republika Srpska President Dragan Mikerevic promised that the request would be met fully as soon as possible.
