Tens of thousands of people took to the streets across Germany to protest against the Alternative for Germany (AfD) after the far-right party won a state election by a landslide.

Axar.az reports, citing Al Jazeera, that about 150,000 demonstrators turned out in roughly 20 cities on Saturday, including Berlin, Hamburg and Munich, in rallies organised by Pruef, a campaign group pushing for a ban on the AfD.

Protesters carried signs reading “Ban the AfD now” and “Democracy needs no alternatives.”

“A broad cross-section of civil society is taking to the streets to prevent the enemies of the constitution … from gaining government power,” said Christoph Bautz, head of Campact, another campaign group involved in the protests, which put turnouts at about 25,000 in Hamburg and 12,000 in Munich.

According to police, several thousand more joined separate demonstrations in Berlin.

The AfD held its own counter-rally in the German capital, attended by Kristin Brinker, the party’s lead candidate for Berlin’s upcoming regional election.

The protests follow a stunning result for the AfD in Saxony-Anhalt, a state in eastern Germany, where the party took nearly 44 percent of the vote on September 6 — far ahead of the roughly 17 percent won by Chancellor Friedrich Merz’s Christian Democratic Union (CDU), which has long dominated German politics.
