The Telegraph has obtained a very rare, unmasked and unguarded discreet footage of the most notorious Islamic State of Iraq and the Levant (Isil) jihadists; torturers, beheaders and serial killers who absconded the UK to fight in Syria.

The foremost media house wrote in a tweet: “#EXCLUSIVE: Britain’s most notorious Isil terrorists unmasked together for the first time”

The men are Mohammed Emwazi, the executioner who beheaded two Britons and three Americans in a propaganda video, Junaid Hussain, Isil’s number one hacker and husband of the UK’s most-wanted woman Sally Jones, Reyaad Khan, who recruited dozens of Britons to fight for Isil, and Raymond Matimba, a Christian convert and sniper. They met regularly at a cafe in Raqqa.

London has experienced four terror attacks since January, three of which was claimed by ISIS. The latest of which was the September 15 underground subway bombing that left several people injured.
