Thousands have assembled in Paris to show solidarity with journalists and to remember those who have been killed during the massacre at Charlie Hebdo.
Rallys took place at Place de la Republique holding signs which read ” Je suis Charlie”, “I am Charlie”.
Thousands of people took to Facebook and Twitter in support of the publication and the cartoon, saying freedom of expression must be defended.
Charlie Hebdo’s offices were firebombed in 2011 after it published an issue poking fun at the Muslim prophet.
Muslims also denounced the weekly for later publishing a series of crude comics of the prophet.
Wednesday’s shooting coincides with the launch of a controversial French book depicting France’s election of its first Muslim president. Charlie Hebdohas featured the cover of the book, “Submission,” on its cover.
Meanwhile, Danish media group JP/Politikens Hus, whose newspaper Jyllands-Posten published cartoons in 2005 depicting the Prophet Muhammad, has increased its security level because of the Parish shooting, an internal email showed.
Jyllands-Posten’s publishing of the cartoons sparked a wave of protests across the Muslim world in which at least 50 died.
