Rock star Sting was to reopen the Bataclan, the revered Paris concert hall where jihadists massacred 90 people, with a hugely symbolic show to mark the first anniversary of France's bloodiest terror attacks.

Scores of survivors of the Bataclan assault -- the worst of the gun and suicide attacks across the city that night which left 130 dead -- will attend the concert, the dominant event in a weekend of otherwise low-key commemorations.

On Friday, November 13, 2015, a night of horror began with three suicide bombers who blew themselves up outside the Stade de France national stadium.

Other Islamic State gangs opened fire on defenceless people on cafe terraces, but the worst nightmare was in the Bataclan, where cowering or wounded concert goers were coldly shot dead one by one.

In comments published yesterday, France's Prime Minister Manuel Valls vowed to end "Islamist terrorism" once and for all.

"(People) are concerned, we owe them the truth. Yes, terrorism will strike us again," warned Valls in a statement published by several European newspapers.

"But yes, we have in ourselves all the resources to resist and all the strength to beat it. We Europeans will defeat Islamist terrorism!"

Today, French President Francois Hollande and Paris Mayor Anne Hidalgo will unveil plaques to the victims outside the national stadium, the Bataclan and bars and restaurants targeted that night.

A year later, nine people out of the around 400 injured in the rampage are still in hospital.
