Fueling fears of clashes, Vucic's supporters have been camping in central Belgrade in front of his headquarters. The crowd included ex-members of a dreaded paramilitary unit involved in the assassination in 2003 of Serbia's first democratic Prime Minister Zoran Djindjic, as well as soccer hooligans who are known for causing violence.

The rally was part of a nationwide anti-corruption movement that erupted after a concrete canopy collapsed at a train station in Serbia's north in November, killing 15 people.
