TOPSHOTS Members of the French police special force GIPN carry out searches in Corcy, northern France, on January 8, 2015 as part of an investigation into a deadly attack the day before by armed gunmen on the Paris offices of French satirical weekly Charlie Hebdo. 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 on January 8 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 January 7's bloodbath at Charlie Hebdo magazine in Paris, the worst terrorist attack in France for half a century.
