Riot police fired tear gas at thousands of anti-government protesters in Serbia’s capital on Saturday. The major rally in Belgrade against Serbia’s populist president, Aleksandar Vucic, was called to back a demand for an early parliamentary election.

Thousands of people in Serbia have set up street blockades, demanding the release of anti-government demonstrators arrested during clashes with police.

Serbia's president announced Sunday more arrests of anti-government protesters following clashes with police at a massive rally demanding an early parliamentary election. Dozens have already been detained.
