In the sensational interview, Rachid Kassim claimed beheading ISIS prisoners was 'a pleasure' and said that the saddest thing about fleeing France for Syria was that of leaving his pet cat behind.
Kassim became one of the world's most wanted men after he was linked to a string of terror attacks in Europe; which includes the murder of a Catholic priest near Normandy in France, and the slaughter of a policeman and his partner near Paris.
The 29-year-old also appeared in a propaganda video for Islamic State just six days after Mohamed Lahouaiej Bouhel murdered 86 people in the 'July Nice terror attack', which took place on Bastille Day. Kassim is also believed to have run an encrypted app called Telegram, which is used by jihadists to share tips on how to carry out terror attacks. The app was taken offline by French security services in September.
When asked how it had felt to behead a prisoner, he said: 'To behead an animal, it would be difficult, with enemies of Allah, it is a pleasure.' He revealed that he fled France after being placed under constant surveillance because of his radical views. He left for Syria in the middle of the night, taking his wife and young daughter with him with just 1,500 Euros in his pocket.
'I thought of attacking France when I was there, and my family was afraid because of it,' he said. 'The cops knew about me. Every time I went jogging, there were always two cops following me. Then they hide. It was ridiculous. 'We left everything behind. Especially my cat. I had a wonderful cat that I left in Gaziantep. It was one of the saddest things about my hijrah (migration to Syria).'Kassim is also known as Ibn Qassim.
