Serbian police cleared street blockades in Belgrade early Monday after protesters demanding early elections used fences and trash bins to block roads and bridges.

The protests follow the arrest of anti-government demonstrators after a massive student-led rally calling for a snap vote to oust President Aleksandar Vucic’s government.

Unrest began after a train station canopy collapse killed 16 people, fueling anger over alleged corruption.

Clashes over the weekend injured dozens of police and protesters, ABC News has reported.

Authorities have arrested university students on charges of plotting attacks, while critics accuse Vucic of authoritarianism and suppressing dissent.
