Legendary Paris rock venue, the Bataclan, has reopened with an emotional gig by the British singer Sting, a year after jihadi gunmen burst in and killed 90 people during a series of terrorist attacks in the French capital. The former Police frontman, 65, appeared on stage to cheers as hundreds of concert-goers including families of the victims and survivors, crowded together struggling to comprehend how gunmen could have burst into the venue – now completely refurbished to cover up its lasting scars, including a new stage and red velvet curtains – and opened fire on music fans in one of the most brutal attacks on French soil since the second world war.
