TOPSHOTS Members of the GIPN and RAID, French police special forces, walk in Corcy, northern France, on January 8, 2015 as they carry out searches 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.
