Since the 1995 Paris Métro and RER bombings, France has been sporadically targeted by Islamist organisations, notably the "Charlie Hebdo" attack in January 2015 which provoked the largest public rallies in French history, gathering 4.4 million people, the November 2015 Paris attacks which resulted in 130 deaths, the deadliest attack on French soil since World War II and the deadliest in the European Union since the Madrid train bombings in 2004, as well as the 2016 Nice truck attack, which caused 87 deaths during Bastille Day celebrations. Opération Chammal, France's military efforts to contain ISIS, killed over 1,000 ISIS troops between 2014 and 2015.
