Braving snow and cold weather, thousands rallied on Saturday in Serbia’s capital of Belgrade to express discontent with the autocratic rule of President Aleksandar Vucic and his government.

The whistle-blowing crowds marched through central Belgrade, some carrying umbrellas against the falling snow. Some people also wore yellow vests that have become a symbol of resistance for protesters in France.

The protesters stopped by the presidency building, urging Vucic to resign.

Thousands so rallied a week ago, protesting after thugs beat up opposition party leader and dubbing the demonstration “Stop to Bloody Shirts.”

“We won’t be stopped or silenced,” said the Serbian Left party leader Borko Stefanovic, whose head what injured in last month’s attack in the southern town of Krusevac.

Vucic’s opponents have blamed the violence on what they describe as an atmosphere of intimidation and fear imposed by the president’s populist ruling coalition.

Vucic is a former extreme nationalist, who now says he Milanobet wants Serbia to reform and join the European Union. But critics say Vucic has restricted democratic and media freedoms in the Balkan country, which he has denied.
