Muslims around the world are continuing to protest after a number of newspapers printed cartoons they found offensive.
One of the cartoons, which first appeared in Denmark, show the Prophet Muhammad wearing a headdress which is shaped like a bomb.
Some Muslims say this is an attack on their religion, and are very angry.
The head of the United Nations, Kofi Annan, has asked the protestors to accept an apology from the Danish paper which first showed the cartoons.
In Syria, protestors have set fire to the Danish and Norwegian embassies in Damascus.
Hundreds of people have gathered outside the Danish embassy in London, with placards speaking against the cartoons.
The publishing of the cartoons has also raised the subject of free speech.
In many countries - including the UK - the right to say anything you want is very important, but some people say that doesn't mean you should be able publish images that are offensive.
