What happened in Zagreb?
According to Croatia's Ministry of the Interior, the attack followed a period of preparation in which members of the group obtained a stolen vehicle, watched Pukanić's home and the NCL Media/Nacional premises, rented a nearby apartment and obtained an explosive device and scooter. On the day of the killings, the scooter carrying the device was brought into the Nacional courtyard at Palmotićeva 3.
The ministry reported that at about 6:27 p.m., as Pukanić and Franjić approached the vehicle used by Pukanić, the explosive device was activated. Both men were killed. Two other people were injured, and vehicles and nearby buildings were damaged.
The investigation and prosecution
Police announced the results of the operation known as Balkan Express eight days after the killings. The early investigation focused on a group accused of preparing and carrying out the bombing. The case later developed into a major organized-crime prosecution before the Zagreb County Court.
On November 3, 2010, six defendants were convicted for their roles in the murders: Robert Matanić, Luka Matanić, Amir Mafalani, Željko Milovanović, Bojan Gudurić and Slobodan Đurović. The first-instance court imposed prison terms ranging from 15 to 40 years.
Appeals and final sentences
Appellate review changed several sentences but left the murder convictions in place. In July 2012, Croatia's Supreme Court increased Robert Matanić's sentence to 35 years, Bojan Gudurić's to 33 years and Slobodan Đurović's to 25 years. It confirmed 40 years for Željko Milovanović and 16 years each for Luka Matanić and Amir Mafalani.
Because the defendants with sentences above 20 years had another level of appeal available, the Supreme Court considered those cases again. In a decision reported on February 6, 2013, Đurović's sentence was reduced from 25 to 23 years; the sentences for Robert Matanić, Milovanović and Gudurić were upheld. HINA described the resulting judgment as final for those defendants.
What did the courts establish about the defendants' roles?
Contemporary reporting on the judgments described Robert Matanić as organizing the group, Milovanović as the direct perpetrator who activated the explosive device, Gudurić as positioned as a backup gunman if the bomb failed, and Đurović as a link in the murder-for-hire chain. Luka Matanić and Mafalani were convicted of participation in the plot.
What remained unresolved?
The Croatian trial did not establish a definitive motive or identify the ultimate person who commissioned the killing. That distinction matters: final convictions for carrying out and facilitating the assassination are not the same thing as proving who, if anyone beyond the convicted group, ultimately ordered it.
Parallel proceedings in Serbia did not close that gap. In 2015, a Belgrade appeals court acquitted Sreten Jocić of organizing Pukanić's murder while upholding a 40-year sentence against Milovanović for carrying it out. The Croatian case therefore has adjudicated perpetrators but an unresolved commissioning question.
Current status check
The legal status used on this page is based on the final Croatian judgments and later reporting. A May 2024 HINA report concerning a separate European Court of Human Rights decision still described Amir Mafalani as one of those convicted for the assassination; that later proceeding concerned monitoring of his correspondence with his lawyer, not a reversal of the Croatian murder judgment.

Frequently asked questions
When were Ivo Pukanić and Niko Franjić killed?
They were killed on October 23, 2008, in Zagreb, when an explosive device placed on a scooter was detonated outside the Nacional/NCL Media premises.
How many people were convicted in Croatia?
Six defendants were convicted for roles in the assassination. Their Croatian prison sentences ultimately ranged from 16 to 40 years after appellate review.
Why is the case marked Solved / Adjudicated if the commissioner is unknown?
The site uses that status because the murders resulted in final convictions establishing criminal responsibility. The page separately preserves the unresolved question of who ultimately commissioned the attack and why.
Was Sreten Jocić convicted of ordering the murder?
No. A Serbian appeals court acquitted him of organizing Pukanić's murder in 2015. That is one reason this page does not present the commissioning question as resolved.
