Protesters drown out interview with AfD party leader Weidel in Berlin

A TV interview with Alice Weidel, the leader of the far-right Alternative for Germany (AfD) party, was almost drowned out by the noise made by demonstrators in Berlin on Sunday.

The open-air talk in the government district on the banks of the Spree river was accompanied by protests with whistles, honking horns and loud music, with demonstrators chanting anti-AfD slogans from across the other riverbank.

A small group of protesters and a large bus could be seen on the other side of the Spree.

Weidel had to lean forwards at times in order to understand the questions posed by presenter Markus Preiß.

The interview is part of a series of summer interviews held by public broadcasters ARD and ZDF with leading German political figures.

Preiß acknowledged the "difficult conditions," saying that at times it was almost impossible to understand each other.

The activist group Zentrum für Politische Schönheit (Centre for Political Beauty) said it was behind the disruption and explained that it has equipped its so-called Adenauer bus with extremely powerful loudspeakers for such purposes.

A spokesman for Berlin police said that a loud song had been played "with the technical equipment of the so-called Adenauer bus."

Twenty-five people took part in the action, according to police.

The police then ended the unannounced action. No one was detained.
