The protesters, defying an anti-virus ban on gatherings, threw bottles, rocks and flares at police who were guarding the parliament building, and police responded with tear gas to disperse the angry crowds.
Similar clashes erupted twice earlier this week. The protests first started when populist President Aleksandar Vucic announced a strict curfew for this weekend to curb a surge in new coronavirus cases in the Balkan country
Vucic later scraped the plan to impose the lockdown. Authorities instead banned gatherings of more than 10 people in Belgrade, the capital, and shortened the working hours of indoor businesses.
Many in Serbia accuse the increasingly authoritarian Vucic and his government of letting the virus crisis spin out of control in order to hold a parliamentary election on June 21 that tightened the ruling party’s grip on power.
