London, Mar 1 : An art gallery put up in Berlin by a Danish group with the objective of opposing religious extremism has been temporarily closed following threats from unidentified persons, believed to be Muslims, who opposed one of the posters describing the Kaaba as a "stupid stone".
The poster showed the Kaaba - the black granite cube-shaped building in Mecca and the words "stupid stone" superimposed on it in German, reported the BBC.
The exhibition was organised by the Danish group Surrend.
Among the 22 posters on display, this particular poster also showed the faithful walking around it with speech bubbles saying "Zionist occupied government", which referred to the title of the exhibition.
The director of the art gallery in Berlin said there had been threats of violence if the poster was not removed, so they had decided to shut for a while. But, he also expressed concern about groups of individuals censoring art.
The art group Surrend says its mission is to make fun of the world's powerful men and crazy ideological conflicts, using stickers, posters and advertisements.
In 2006 the same group took out an advertisement in an Iranian daily with a picture of Iran President Mahmoud Ahmadinejad expressing support for his fight against US President George Bush. The text of the advertisement was carefully arranged so that the letters at the start of every line spelled out the word "swine" when read vertically.
