It is a year since terrorists launched co-ordinated attacks in Paris and slaughtered 130 innocent people. The worst assault on November 13 last year occurred at the Bataclan nightclub, an historic theatre, where gunmen massacred 90 music fans at a show by an American band, Eagles of Death Metal.
The Islamic State militants opened fire with automatic weapons as the group started their song Kiss the Devil.
As the attacks unfolded across the city, the level of planning revealed a degree of French vulnerability which seemed to catch the authorities by surprise. The shock intensified when it emerged that some of the attackers were young French men who had been trained by Islamic State in Syria.
Isis claimed the attacks were in retaliation for French airstrikes on targets in Syria and Iraq. The scale of the Paris atrocities were unsettling, given that the Republic was no stranger to terrorist strikes.
In January last year gunmen claimed 17 victims after they stormed the satirical newspaper Charlie Hebdo in Paris and attacked a kosher grocery store.
