Serbians angry over a looming coronavirus curfew stormed the country’s parliament building during a series of violent clashes with police that now have officials wondering whether they should proceed with the measures.

The chaos that erupted in Belgrade on Tuesday came after health officials reported the highest single-day death toll of 13, as well as 299 new COVID-19 cases. Serbian police say 23 people have been detained and scores of police officers and demonstrators were injured in the violence that lasted for more than six hours.

“You know, seven days ago I thought to impose once again the lockdown of the entire country because of that new wave of the COVID-19 crisis,” President Aleksandar Vucic said Wednesday, a day after announcing that a weekend curfew will be reintroduced in the Balkan country.
