Islamist foursome including notorious Jihadi John laugh and joke in Raqqa coffee shop in secret footage

Remarkable secret footage showing the notorious British jihadi quartet known as the 'Beatles' has emerged.

In the video - which was recorded with a camera phone hidden under a coat - the ISIS fighters can be seen speaking calmly in a Syrian cafe popular with British fanatics.

Mohammed Emwazi, the vicious murderer who beheaded two of his fellow Britons on camera, can be seen looking at his phone while occasionally chatting to Reyaad Khan.

Khan, a student from Cardiff, was considered one of the most effective recruiters for the extremist group.

The extremely rare footage, which has been obtained by The Telegraph, shows the group completely relaxed as they charge their mobile phones.

To the cameraman's left is Junaid Hussain, known as the murderous organisation's hacking expert and as the husband of the terrorist Sally Jones.

And to his right is the sniper Raymond Matimba, believed to be the only man in the room other than the cameraman to still be alive.

They can be heard discussing fairly banal topics such as bank accounts during the 90-second clip.

The Telegraph's source - cultivated for over two years by reporter Josie Ensor - also told the paper about life in the ISIS capital of Raqqa, Syria.
