The Belgrade daily said that the Embassy declined to comment on the information, explaining that high-level talks between Bulgarian and Serbian-Montenegrin authorities were under way and that Embassy officials were fully occupied with the case.
Brankovic arrived in Bulgaria as a member of a delegation of the Serbia and Montenegro Army and was arrested in Sofia on Tuesday. A Bulgarian court released him on Thursday, citing diplomatic immunity, and the prosecutors filed an appeal.
Serbian media say that the competent court will decide next week whether Brankovic will be extradited to Croatia or will return to Serbia.
The county court in Sisak, about 50 kilometres southeast of Zagreb, has initiated an investigation on suspicion that Brankovic was involved in war crimes committed in 1991 in the Novska area, about 100 kilometres east of Zagreb.
Zoran Dragisic of the Faculty of Civil Defence in Belgrade told Danas that Serbian intelligence services had information that Brankovic was on an Interpol red warrant, but that the information was not taken seriously.
Dragisic said that Serbia and Montenegro should urgently settle the issue with Croatia "because his only fault is that he took part in the war." He noted that Dragisic had been "a member of the legal armed forces at the time the events he is charged with took place."
