The Times adds that two other Nacional employees were injured in the blast, which occurred in the newspaper's parking lot.
Agence France-Presse (AFP) writes that Mr. Pukanic was "one of Croatia's most controversial journalists" and was best known in Croatia for a 2003 interview with Croatian general Ante Gotovina, who at the time was fleeing a war crimes indictment issued by The Hague. Pukanic was also accused of having ties to Croatia's organized crime, which the Croatian Journalists' Association took to task for his murder.
The Croatian Journalists' Association (HND) voiced outrage at the murder and called on the authorities to "immediately declare a war on criminals and murderers."
"What has occurred is horrible and it shows that crime has severely expanded in Croatia," the HND said in a statement.
