Islamic State of Iraq and Syria (ISIS) militant Mohammed Emwazi, popularly known as Jihadi John, has reportedly vowed to kill "non believers" after returning to Britain.
According to the Daily Star, ISIS released a new video wherein a man was shown as being a notorious fanatic who was later unmasked as Jihadi John.
In the chilling one-minute video, he turns to the camera and warns, "I will carry on cutting heads."
According to reports, Emwazi planned to return to Britain to behead non-believers.
Jihadi John is believed to have beheaded at least seven hostages in Syria including Brits David Haines and Alan Henning.
He had also apparently beheaded Japanese journalist Kenji Goto.
