Norway isn't a member of the European Union, but that didn't seem to dissuade the activists. They hailed from the political group al-Yasser, according to the Associated Press on the scene.
The activists also sprayed photos of both the Norwegian and Danish flags with black paint.
Around 15 armed men were behind the demonstration against Norway and Denmark, where the caricature was first printed in the newspaper Jyllands-Posten. Any illustration of the prophet Mohammed is offensive to Muslims, and the activists won't tolerate others' beliefs in freedom of expression.
Gudrun Bertinussen, a Norwegian aid worker for Norwegian People's Aid (Norsk Folkehjelp) in Gaza, said that Norwegians generally have been well-received by the Palestinians. She noted, however, that the publication of the Mohammed caricature in a small Christian magazine has provoked Muslims.
Norway's Foreign Ministry is urging Norwegians in Gaza to heed warnings by angry Muslims to leave the area within the next 48 hours. Muslim activists have also organized a boycott of Danish products, some Muslim countries have recalled their ambassadors from Denmark and Arab groups were seeking support from the UN.
The umbrella group for Islamic groups in Norway, (Islamsk Råd Norge, IRN), is demanding an apology from the Christian publication Magazinet that published the caricature in Norway. A spokesman said the group supports freedom of expression, but not that which injures or offends others.
