The U.S. has taken on the job of doing Radojcik's words about the attack, Hovenier: We're working on who's responsible.

The US diplomat has said the US is doing its job to find out who is behind the September 24th attack, even though Milan Radojicic in his letter has admitted to lag behind organising the terrorist attack.

We're looking at the specifics. Some things we know. What we know is the quantity and quality of weapons these attackers had, who were ethnic Serbs. That suggests they didn't do this head on their own, some structures were behind that. What we do know now is that an individual who was vice president of the ethnic Serb party in Kosovo, participating in events with top Serbian officials, has announced through the lawyer that he was organising this event and that he was present. We're still doing our job about who's in charge and this is going on. But now we know more about it and we're worried about what happened. And those responsible believe they have to account for”, Havener said.
