Chilling new details from a deadly terrorist attack at the Hyper Cacher kosher supermarket in Paris last month emerged Friday when a reported transcript of footage from the incident surfaced.

In the nearly eight-minute-long video filmed on a GoPro camera by Amedy Coulibaly, the Islamist gunman can reportedly be seen shooting three of the four victims and delivering an anti-Semitic rant.

The footage shows Coulibaly first grabbing hold of a customer, requesting his name, and then shooting him dead, reports said. The gunman goes on to ask another man for his origin, then kills him after the man replies “Jewish,” according to the BBC, quoting French reports.

“So you know why I am here then, Allahu Akbar,” Coulibaly proceeds to shout, according to a Le Nouvel Observateur report. The gunman can also be heard making anti-Semitic remarks as hostages cry out that the victims have done no wrong.

Four men were killed in the attack shortly before the start of Shabbat on Friday afternoon, January 9: Yohan Cohen, 22, an employee of the HyperCacher store; Yoav Hattab, 21, a student of Tunisian origin and the son of the chief rabbi of Tunis; Phillipe Barham, 45, an executive at an IT company, a father of four and the brother of a rabbi; and François-Michel Saada, 64, a retired father of two.

Coulibaly reportedly told a French journalist at the height of the siege that he had deliberately chosen to target Jews.

According to testimony by one of the hostages who painted a horrific picture of the seven-hour siege inside the supermarket, Coulibaly, a self-proclaimed Islamic State member, was calm, collected, somewhat chivalrous, boastful of the murders he committed and attention-hungry during the attack.

Coulibaly’s attack came two days after co-terrorists Said and Cherif Kouachi gunned down 12 people at the Paris offices of satirical magazine Charlie Hebdo, and a day after he himself shot and killed a policewoman as part of a coordinated series of attacks that shook France. The killing sprees culminated in twin sieges that ended with all three gunmen dead.
