Aerial view taken on January 11, 2015 shows people attending the Unity rally Marche Republicaine at the Place de la Republique (Republique’s square) in Paris in tribute to the 17 victims of a three-day killing spree by homegrown Islamists. 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.
