A neo-Nazi group announced earlier this week a planned protest outside the Rockhal following a concert by German band Söhne Mannheims on Saturday evening.

The group, called Kameradschaft Nationaler Widerstand Zweibrücken (NWZ), made the announcement on its Facebook page, saying it wanted to show “solidarity with Horst Mahler on the occasion of a performance of the Söhne Mannheims”.

The Rockhal upped their security ahead of the planned protest and around 30 policemen were present outside the concert hall.

But despite the announcement, the group did not turn up.

Around 30 silent counter protesters were at the location who, following permission, distributed information to passers by and those going to the concert.

The town of Esch-sur-Alzette warned on Friday that it had not given authorisation for the NWZ protest — named ‘Marionettes put our people in chains: freedom for Horst Mahler’ — to be held.

A request for authorisation was sent to the town of Esch-sur-Alzette by email, but it was refused for “security reasons”.

A town official said: “In addition to our obligation to guarantee the security and maintenance of public order, the town of Esch-sur-Alzette, which is a member of UNESCO’s International Coalition of Cities against Racism, stresses that the subject of the manifestation is absolutely incompatible with the principles of the constitution of the Grand Duchy of Luxembourg and the values ​​of Luxembourg society as a whole.”
