Protesters opposing Covid-19 restrictions in Bulgaria have clashed with police as they tried to storm parliament in the capital of Sofia.

A heavy police presence prevented protesters from entering the building and some were detained.

Several people, including police officers, were injured during the clashes. Eventually, the protesters were pushed back and police cordoned off the building.

The violence erupted at a rally against mask and vaccine mandates organised by a nationalist group opposing the government’s anti-coronavirus measures.

“The aim of the protest is to remove the restrictive measures and especially, first of all, the unconstitutional green certificate,” Kostadin Kostadinov, leader of the Vazrazhdane party, said ahead of the protest.

The nationalist group, which holds 13 seats in parliament’s 240-seat chamber, has won support among opponents of coronavirus restrictions.

Nearly 1,000 protesters, who waved national flags and sang patriotic songs, remained at the square in front of the National Assembly, saying they planned to stay there until their demands for abolishing mandatory face masks and vaccination status passes are met.

Bulgaria, which is facing a new surge in infections, is the least vaccinated country in the 27-member European Union, with only a third of its population fully vaccinated against Covid-19.

Speaking from his home, where he is quarantined for contact with an infected person, Prime Minister Kiril Petkov called for calm and invited representatives of the protesters to his office on Friday to discuss their demands.
