( dpa ) - Authorities in Berlin have closed down an exhibition of works by the Danish art group Surrend after protests by Muslims, organizers said Thursday.
The protesters threatened to use violence if a series of satirical posters were not withdrawn from the exhibition at a city-centre gallery, the local arts council said.
One of the 21 posters on display depicts Islam's holiest place, the cube-like Kaaba in Mecca, with the words "Stupid Stone" written above it.
The exhibition was opened on February 22 by the president of Berlin's Academy of Arts, Klaus Staeck.
Surrend, which was formed in 2006, has designed a series of posters poking fun at world leaders.
In December 2006, it placed an advertisement in a small Tehran newspaper insulting Iranian President Mahmoud Ahmadinejad with a hidden message spelling out the word "swine"
