The attacks on Paris were the worst terrorist assault on Europe in a decade.
On this, the one year anniversary of the attacks, it's worthwhile reminding ourselves how the events of the tragic evening of Friday 13 November unfolded.
The first explosion went off at around 8:20pm near the Stade de France, where President Francois Hollande was at a football match between France and Germany. At this stage it was reported that one person had been killed by the blast, and the body of a terrorist was found at the scene wearing a suicide belt filled with shrapnel.
Five minutes later, gunmen with Kalashnikovs opened fire at Le Carillon bar and Le Petit Cambodge restaurant in Rue Alibert in the city's 10th district, killing 15 and injuring 10.
At 8:30pm a second explosion goes off outside the Stade de France when a second suicide bomber blew himself up.
Within the next 10 minutes, three more attacks are carried out in the same area. Five people die in a shooting outside La Bonne Biere bar in the 11th district, another 19 are killed at the nearby La Belle Equipe restaurant, and one person is seriously injured when a suicide explosive is detonated inside the Voltaire restaurant.
At around 9:40pm three gunmen storm Le Bataclan during a concert by Eagles of Death Metal. Half an hour later, a hostage crisis in the theatre is confirmed.
Not long after, a third suicide bomber blows himself up near the Stade de France.
At around 11pm, Hollande places the whole of France under a state of emergency and the military is called into the centre of Paris. President Obama then issues the statement: "We stand together with them in the fight against terrorism and extremism."
By 12:20am on Saturday, the three terrorists at Le Bataclan are dead. One is shot by police, and the other two blew themselves up after armed officers stormed the building. At least 89 are killed and more than 100 others injured as the attackers fire at the crowd and throw explosives. The attackers are heard mentioning Syria and Iraq during the massacre.
At around 1:40am, police say they believe all the attackers involved in the string of attacks are dead. They add that a hunt is under way for possible accomplices.
In total, 130 people died during the horrific attacks, and today is a chance to remember the needless loss of life.
Sting is set to mark the occasion with a concert reopening the Bataclan venue, and various other commemorations will take place across Paris.
