How the world's cartoonists are responding to the Charlie Hebdo attack

Video report by ITV News International Affairs Editor Rageh Omaar

Masked gunmen targeted the offices of French satirical magazine Charlie Hebdo today, killing 12 people.

Prominent cartoonists Jean Cabu, Stephane Charbonnier, Georges Wolinski and Bernard "Tignous" Verlhac were among the victims.

The provocative magazine is believed to have been targeted because it had previously published cartoons mocking the Prophet Mohammad.

Cartoonists from across the world have responded by showing solidarity with their colleagues and standing up for free speech.
