Tomislav Nikolic may have put his ultra-nationalist political affiliations behind him, but recent comments by Serbia's new president about the bloody wars of the 1990s have left neighbours alarmed.

In recent comments to the media, Nikolic said that the mass killings in Srebrenica during the Bosnian war did not constitute "genocide", and seemed to justify the conquest of Vukovar during the Croatian war by explaining that it was originally a "Serb city".

Nikolic's remarks have angered his neighbours and prompted concern among some Serbians that he may be endangering the country's chances of entering the European Union.
