Armed members of the French riot police (CRS) get ready to take up a position at Porte de Vincennes in Paris on January 9, 2015, after at least one person was injured when a gunman opened fire at a kosher grocery store and took at least five people hostage, sources told AFP. The attacker was suspected of being the same gunman who killed a policewoman in a shooting in Montrouge in southern Paris on January 8. AFP PHOTO / LOIC VENANCE
