Riot police used tear gas against anti-government protesters in Belgrade when clashes broke out on Thursday evening.

Protesters threw flares and chanted as they took to the streets of the Serbian capital.

It followed a second day of clashes between anti-government protesters and supporters for President Aleksandar Vucic.

The Serbian president has faced accusations of stifling democratic freedoms and of allowing organized crime and corruption to flourish. He denies those allegations.

The student-led protests in Serbia first started in November after a train station canopy collapsed in Novi Sad, killing 16 people and triggering accusations of corruption in state infrastructure projects.

Protests have since drawn hundreds of thousands of people, shaking Vucic’s firm grip on power. His supporters have recently started organizing counterdemonstrations, fueling fears of violence.
