Terrorists opened fire inside the Paris offices of Charlie Hebdo on Wednesday, killing 12 — reportedly including the satirical publication's editor and three cartoonists who mocked radical Islam.

In the wake of the brutal murders, journalists, cartoonists and free speech advocates from around the world are speaking out and offering some powerful cartoons in response.

Author Salman Rushdie issued a statement, calling satire "a force for liberty and against tyranny, dishonesty and stupidity."

Meantime, some media outlets are being called out for blurring the images of the cartoons in their reporting on the attack.

An AP spokesman told Buzzfeed News that it would not show the Muhammad cartoons in accordance with its policy against "moving deliberately provocative images."
