The key to the arrest of the remaining two Hague fugitives is in Serbia and the arrest of generals Ratko Mladic and Goran Hadzic has no alternative, the Chief Prosecutor of the International Criminal Tribunal for the former Yugoslavia (ICTY) Serge Brammertz said Wednesday.

Our main working hypothesis is that the remaining fugitives are in Serbia. There is no reason to believe otherwise. We believe that the key to the arrest of Mladic and Hadzic is in Serbia, Brammertz told reporters after a meeting with Serbian President Boris Tadic.

Asked how his report will affect future decisions regarding Serbia's EU accession, the ICTY prosecutor said that he knows the EU is watching his reports closely.

But my job is to give an objective analysis of what has been done and what needs more work. It is up to others to make political decisions and conclusions, Brammertz said.
