A picture taken on January 12, 2015 in Rome shows front pages of Italian newspapers displaying headlines in response to the recent Islamist attacks that killed 17 people, most at the Paris offices of satirical magazine Charlie Hebdo. Millions marched against terrorism yesterday in the largest protests France has ever seen, led by world leaders in Paris uniting in tribute to the victims of Islamist attacks as the crowd cried "Not Afraid". The interior ministry said nearly four million people took to the streets across the country, with some estimates putting the number in Paris alone at 1.6 million.
