A fourteen-year-old boy has been killed during a demonstration against cartoons that offended Muslims.
The teenager was shot dead by police in Somalia who were being attacked by protesters. Seven others were injured.
Three people were killed in Afghanistan when police opened fire on protestors after a police station was attacked.
The cartoons were shown in newspapers across the world and one shows the Prophet Muhammad wearing a headdress shaped like a bomb.
Muslims are very angry about the cartoons, which some say are an attack on their religion.
Any images of the Prophet - or Allah - are banned under Islamic tradition.
A Danish newspaper was the first to print the cartoons, in September 2005, and others have since reprinted them.
Other protests have been taking place from Gaza to India, Indonesia and Iran.
Weekend protests
On Saturday protestors in Syria set fire to the Danish and Norwegian embassies, which has angered the governments of the Scandinavian countries.
They're not happy that the Syrian government didn't stop the protestors, and the US has also criticised Syria's lack of action.
On Sunday thousands of people took to the streets in Beirut, Lebanon, protesting outside the Danish embassy.
Free speech
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.
