As tens of thousands of police, troops and government employees searched for the two suspects -- brothers Said and Cherif Kouachi -- who authorities said killed 12 people during their Wednesday attack on the satirical newspaper, they were spotted early Thursday morning at a gas station in Villers-Cotterets, outside of Paris.
Gas station surveillance video shows the brothers, still clad in black clothes.
Police flooded the scene and began zeroing in on the surrounding countryside towns the Foret-de-Retz, approximately 50 miles northeast of Paris.
Police descended on the town of Crépy-en-Valois, not far from the gas station where the spotting was reported, and they sealed off the village.
Heavily armed police were then spotted on the other side of the forest in the villages of Longpont and Corcy, where they searched door to door.
