Twelve people, including 10 journalists and two security officers were killed at the headquarters of the French satirical magazine Charlie Hebdo in Paris yesterday.
Among those were Georges Wolinski, Stephane Charbonnier, Bernard Verlhac and Jean Cabut, four of France's most respected cartoonists.
Striking images drawn by cartoonists have emerged from across the world after the attack provoked an outcry online by people in support of free speech.
