Artists in the western German city of Dortmund have sprayed over neo-Nazi graffiti in a street that far-right extremists have long claimed as their territory.
Under the watchful eye of Dortmund police, the artists covered neo-Nazi slogans with colorful images in the city's Dorstfeld district early Friday.
The move was commissioned by a civil society group called Association for Diversity, Tolerance and Democracy, and sanctioned by city authorities and police.
City authorities said the far-right graffiti has been "a thorn in the eye'' for years, used by neo-Nazis to "intimidate and scare away people who think differently.''
The top security official in North Rhine-Westphalia state, Herbert Reul, said neo-Nazis "mustn't be given a millimeter's room.''
Dorstfeld has in the past seen numerous violent attacks by far-right extremists.
