Fears deadly brothers will attack again

French anti-terrorism police converged on an area northeast of Paris after two brothers suspected of being behind an attack on a satirical newspaper were spotted at a gasoline station in the region.

Prime minister Manuel Valls said he feared the Islamist militants who killed 12 people could strike again as a manhunt for two men widened across the country.

Two police sources said that the men were seen armed and wearing cagoules in a Renault Clio car at a petrol station on a secondary road in Villers-Cotterets some 70km from the French capital.
