When the organisation Islamic Society in Denmark toured the Middle-East to create awareness about the cartoons, they also brought 3 additional images. The first of the three additional pictures, which are of dismal quality, shows Muhammad as a pedophile demon, the second shows Muhammed with a pig snout and the third depicts a praying Muslim being raped by a dog.
Akhmad Akkari, spokesman of the 21 Danish Muslim organizations which organized the tour, explained that the three drawings had been added to "give an insight in how hateful the atmosphere in Denmark is towards Muslims." Akkari claimed he does not know the origin of the three pictures. He said they had been sent anonymously to Danish Muslims. However, when Ekstra Bladet asked if it could talk to these Muslims, Akkari refused to reveal their identity. These images had however never been published in Jyllands-Posten. The society also allegedly exaggerated its membership and the hardships of Muslims in Denmark, for instance claiming to represent 200,000 angry Muslims, when the actual number was in fact fewer than 15,000. [26].
BBC World also aired a story showing one of the three non-published images, on 2006-01-30, and wrongly claimed it had been published in Jyllands-Posten[27].
Other rumours of misinformation include the statement that Jyllands-Posten is a governmentally owned newspaper. Spokesman for the Danish delegation Muhammed al Samha and delegation member Ahmed al-Harbi in the Egyptian newspaper al-Ahram quoted the following answer to the question on when they first sensed a crisis that needed a breaking of silence: "It was when Jyllands-Posten, a newspaper belonging to the ruling Danish party - an extreme right-wing party, publishing drawings and sketches of the prophet Muhammad." This caused the Danish Prime Minister Anders Fogh Rasmussen to demand an apology from the Islamic Society in Denmark for spreading lies about the newspaper and the ruling party. [citation needed] Rumours of misinformation also include statements that Danish newspapers are running a campaign against Islam and that the Danish government is planning to publish a censored version of the Koran. [citation needed]
Ahmad Abu Laban, the leader of the organisation Islamic Society in Denmark, has misinformed on Al Jazeera[28], that we should be enjoyed if someone chooses to boycot Denmark. However, in other media, he recommends not to boycot Denmark, and says he will work actively to prevent further boycot.
