A huge manhunt for two brothers suspected of massacring 12 people in an attack at a satirical French weekly zeroed in on a northern town Thursday 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.
The discovery of the car, abandoned in the northern town of Villers-Cotterets, was a breakthrough in the frantic police hunt.
Earlier reports said that the two figutives, Franco-Algerians Said Kouachi, 34, and Cherif Kouachi, 32, had been spotted at a petrol station in the same area.
One of the suspects, Cherif Kouachi, had already served time on terrorism charges and had a history of funneling terrorists to Iraq.He and his brother, Said, should be considered "armed and dangerous," French police said in a bulletin early on Thursday, appealing for witnesses after a fruitless search in the city of Reims, in French Champagne country.
