A man holds a placard which reads “I am Charlie” to pay tribute during a gathering at the Place de la Republique in Paris January 7, 2015, following a shooting by gunmen at the offices of weekly satirical magazine Charlie Hebdo. Gunmen stormed the Paris offices of the weekly satirical magazine Charlie Hebdo, renowned for lampooning radical Islam, killing at least 12 people, including two police officers in the worst militant attack on French soil in recent decades. The French President headed to the scene of the attack and the government said it was raising France’s security level to the highest notch. REUTERS/Gonzalo Fuentes (FRANCE – Tags: CRIME LAW MEDIA)
