Serbian police detained 71 people after clashes during the fourth night of anti-government protests against the Serbian president that were initially sparked by his plans to reintroduce a coronavirus lockdown, EDNews.net reports citing Associated Press.

Fourteen policemen were injured in the rioting Friday evening when hundreds of right-wing demonstrators tried to storm the parliament building in downtown Belgrade, police director Vladimir Rebic said Saturday. Many demonstrators and several reporters were also injured in the protests.

Hundreds gathered on Saturday for another night of protests when no incidents were reported.

Serbian media reported that among the detained was a former parliament member and one of the leaders of the violent protesters, pro-Russian far-right politician Srdjan Nogo.

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.

Vucic has denied this, although authorities had relaxed the rules prior to the vote, allowing massive crowds at soccer games, tennis matches and nightclubs.

Authorities reported 12 new coronavirus deaths on Saturday and 354 new infections, although there have been increasing doubts about the accuracy of the official figures.

The country officially has over 18,000 confirmed infections and 382 deaths since March. Health authorities have warned that Serbian hospitals are almost full due to the latest surge in cases.

Vucic has claimed that unspecified foreign security services were involved in the unrest and pledged he won’t be toppled in the streets. Some opposition leaders, meanwhile, are blaming the rioting on groups they say are controlled by the government to discredit peaceful protests.

Rebic said foreign citizens are among those detained, including people from Montenegro, Bosnia, Britain and Tunisia. He said police are looking into “foreign element in the radicalization of the protests.”

Serbia is a rare Russian ally in Europe with historically close Slavic ties. The country is bidding to join the European Union after years of crisis and wars in the 1990s. Nationalist and far-right groups in Serbia are opposed to EU membership and want closer ties with Russia instead.

The Russian foreign ministry has vehemently denied any involvement in the latest protests in Serbia.
