French graffiti artist, Combo, 28, was attacked in 2015 by a gang after refusing to take down the above mural calling for religious harmony in Paris. He was left with a dislocated shoulder and bruises across his face after being set upon in a ghetto in the east of the capital. He had just finished the design that featured the word 'coexist' written with a Muslim crescent for letter C, a Star of David as the X and a Christian cross as the 'T'. It was accompanied by a life-size self-portrait and his tag 'combo'. The attack happened a month after the massacre at the Charlie Hebdo newspaper by Islamist extremists.
