Kalinic, who holds both Croatian and Serbian citizenship and who was sentenced in Serbia to 30 years in prison for his involvement in the 2003 assassination of Prime Minister Zoran Djindjic, will be the first Croatian national to be extradited by Zagreb to a foreign country, Devcic said.

Devcic said that Kalinic was called to the County Court this morning to be questioned as a witness, but in the meantime an additional extradition request has arrived, referring to an investigation against Kalinic for involvement in three murders in Belgrade.

At that point, Kalinic only had to say if he agreed to be extradited.

The Zagreb County Court has recently greenlighted Kalinic's extradition to Serbia, and he had three days to appeal.

About a month ago, Kalinic said he did not want to be extradited to Serbia, saying that he feared he would not stand a fair trial in Belgrade.

Today he agreed to be immediately extradited, adding that as far as he was concerned, there were no obstacles to his extradition and he did not intend to appeal.

A bilateral extradition agreement, signed by Croatia and Serbia on 29 June, has removed obstacles to Kalinic's transfer, spokesman Devcic said, but added that due to procedural reasons Kalinic could not be immediately transferred.

The Croatian Justice Minister has to greenlight the extradition decision and sign it, Devcic said.

Serbia requested the extradition of Sretko Kalinic from Croatia on 11 June, three days after he was gravely wounded in a shooting outside Zagreb, where he underwent surgery. It is suspected that he was shot by Milos Simovic, whom the Serbian police arrested two days later while he was trying to illegally cross the border into Serbia. Both were members of the Zemun clan convicted in absence to 30 years' imprisonment each for the assassination of Serbian Prime Minister Zoran Djindjic in 2003.
