A video of the gunman who killed a French policewoman and four other hostages at a kosher grocery has emerged, in which he pledges allegiance to the Islamic State’s attack on Charlie Hebdo, a French satirical newspaper.

The posthumous video which shows Amedy Coulibaly holding a gun, and giving out speeches in front of an Islamic State emblem has been verified by the SITE Intelligence Group, reported AP.

"What we are doing is completely legitimate, given what they are doing," Amedy Coulibaly told the camera in fluent French. "You cannot attack and not expect retribution so you are playing the victim as if you don't understand what's happening.” he said in the video.

Earlier Coulibaly had taken over a kosher grocery, demanding freedom for the brothers who had carried out the attacks at the Charlie Hebdo office.

The brothers then trapped in a printing house near the airport were killed along with Coulibaly.
