A gunman at the wheel of a heavy truck ploughed into crowds celebrating Bastille Day in the French city of Nice, killing at least 84 people and injuring scores more. <br /> <br />The attack - which President Francois Hollande called a terrorist act - is the third mass killing in France since attackers targeted a kosher supermarket and the offices of the satirical magazine Charlie Hebdo in January 2015. <br /> <br />Seventeen people died in Paris in three days of violence that began with the attack by two Islamist gunmen on the offices of Charlie Hebdo on Jan. 7 - in which 12 people were killed - and ended with a siege at a kosher supermarket two days later. <br /> <br />In November, nine militants killed a further 130 people and wounded hundreds more in a number of attacks across Paris. <br /> <br />Some assailants blew themselves up near the Stade de France stadium, others opened fire on downtown cafe terraces and a third group armed with guns and suicide vests killed 90 music fans at the Bataclan rock concert hall.
