Around a dozen Serbian nationalists marked  the first anniversary of Bosnian Serb genocide suspect Radovan Karadzic's arrest with a subdued protest here on Tuesday.

Outnumbered by police, the youths gathered outside the Belgrade offices of  pro-Western President Boris Tadic, some in T-shirts with pictures of Karadzic  and his wartime military commander Ratko Mladic.

"Serbian Hero" and "Those who betrayed Radovan won't see the light of day," said messages stamped on the T-shirts.

After 13 years on the run from a UN war crimes tribunal, Karadzic was captured in the Serbian capital on July 21, 2008. He was travelling on a  suburban bus disguised as a heavily-bearded alternative medicine healer.

The protest was held without incident, unlike clashes between riot police and hundreds of pro-Karadzic youths in Belgrade a year ago which left one person dead.

Karadzic faces 11 counts of genocide, war crimes and crimes against  humanity before the Netherlands-based International Criminal Tribunal for the  former Yugoslavia (ICTY).
 
He denies the charges, which are mainly related to the siege of Sarajevo,  which cost around 10,000 lives, and the Srebrenica massacre of some 8,000  Muslim men and boys during Bosnia's 1992-1995 war.
