Reports via Loudwire confirm there were no injuries following the explosion but representatives for the band have confirmed that the shows were cancelled on order to ensure the safety of everyone.
They wrote vai a now deleted Tweet: "During load in for tonight's performance in Paris, an explosive device was detonated just outside of the venue door.
"Band, crew, the fans in line are all safe, are all safe, and there were no injuries".
"Due to the intimate nature of our 'Personal Space performances, we are unable to guarantee the safety of the fans in attendance."
The intimate venue, Les Etoiles - meaning The Stars - was created as a "café-concert" in 1882.
And according to reports on the UKK website MailOnline, the explosion was firecrackers, thrown by protesters marching against the pension strikes.
