The Eiffel tower’s lights are switched off in Paris on January 8, 2015, in tribute to the twelve people killed the day before in an attack by two armed gunmen on the offices of French satirical newspaper Charlie Hebdo in Paris. A huge manhunt for two brothers suspected of massacring 12 people in an Islamist attack at a satirical French weekly zeroed in on a northern town after the discovery of one of the getaway cars. As thousands of police tightened their net, the country marked a rare national day of mourning for Wednesday’s bloodbath at Charlie Hebdo magazine in Paris, the worst terrorist attack in France for half a century.
