Members of American rock band Eagles of Death Metal laid flowers outside a Paris concert hall where they were playing on 13 November when Islamic State (Isis) gunmen opened fire on the audience, killing 89 people.
It was the first time frontman Jesse Hughes, guitarist Dave Catching, bassist Matt McJunkins and drummer Julian Dorio returned to the Bataclan theatre they escaped in harrowing circumstances surviving the carnage in November.
The four were overcome with emotion as they stood in front the now-shut site, staring at many wreaths and notes left outside in memory of the victims. Some wiped away tears and embraced, while reading messages and tributes posted by family and friends of their fans who died in attack.
The visit came after the band made a surprise comeback on a Paris stage on 7 December, as they were invited to perform at the AccorHotels Arena during a U2 concert.
"There is nothing left except to introduce you to some people whose lives will forever be a part of this city of Paris," U2 frontman Bono told the crowd as he welcomed his US colleagues on stage. "These are our brothers. Our fellow troubadours. They were robbed of their stage three weeks ago, and we would like to offer them ours tonight."
The bands gave a joint rendition of Patti Smith's People Have The Power, and then Eagles of Death Metal sang their song I Love You All The Time.
Some 130 people were killed in the series of coordinated shootings and bombings that hit Paris last month. After the attacks Eagles of Death Metal expressed the desire to be the first to play at the Bataclan, when the concert hall reopens its doors.
