The killings began on January 7 with an assault on the Charlie Hebdo satirical magazine in Paris that saw two brothers massacre 12 people including some of the country’s best-known cartoonists, the killing of a policewoman and the storming of a Jewish supermarket on the eastern fringes of the capital which killed 4 local residents.
