On the night of 13 November 2015, Paris suffered a series of terror attacks. In reaction to those events, many individuals, governments, and other organisations around the world expressed their solidarity with France and with the victims. Many world leaders issued statements, mostly strongly condemning the attacks and vowing to stand by and support France. Public vigils took place in many international cities, and a number of world landmarks were illuminated in the colours of the French flag. Members of the public expressed their solidarity through social media by sharing images, notably the "Peace for Paris" symbol, designed by the French graphic designer Jean Jullien, and through the slogans, "Pray for Paris" and "Je suis Paris" (itself a reference to the phrase "Je suis Charlie", which was shared widely in the aftermath of the "Charlie Hebdo" shootings in Paris on 7 January 2015).
