The Champs-Elysees attack is the latest in a series of atrocities to shock France in recent years.

Here is a timeline of attacks that have left French citizens shocked and changed the nation:

Two masked gunmen walk into the Charlie Hebdo’s offices, a satirical weekly newspaper, and kill 12 people, including cartoonists they single out and call by name.
The magazine’s editor, Stephane Charbonnier, known as Charb, is among the victims.
The gunmen, later identified as brothers Cherif and Said Kouachi, shout “Allahu Akbar” (“God is greatest”) while carrying out the attack, and say they belong the Islamist terrorist group Al-Qaeda’s branch in Yemen.
The attackers escape and Paris is put under maximum alert.

A shooter, later linked to the Kouachi brothers, shoots dead a policewoman in Montrouge, and shoots a man, injuring him.

The violent end
The Kouachi brothers, with police behind them in a high-speed chase, seek refuge in an industrial complex at Dammartin-en-Goele, a town 35km (22 miles) northeast of Paris.
Hundreds of police and special forces besiege the complex, with the brothers holed up inside.
Reports emerge that in the French capital a gunman is holding several people captive in a kosher supermarket, threatening to kill the hostages unless the Kouachi brothers are set free.
The gunman is identified as Amedy Coulibaly – the same person who had been responsible, with accomplice Hayat Boumeddiene, for the killing of the policewoman in Montrouge. Boumeddiene remains at large.
Elite forces storm the supermarket and kill the gunman. They free 15 hostages, and also find the bodies of four people.
Around the same time, the stand-off in Dammartin-en-Goele comes to a brutal close. Amid gunshot and explosions, the two come out of the building firing at police and are killed.
