The world's most wanted man and the face of the most horrific beheadings of this decade, Jihadi John, the masked man with a British accent, has reportedly fled the Islamic State-controlled territory to a another lesser known terrorist group in Syria.

Mohammed Emwazi, a British Kuwaiti computer science graduate who moved to Britain when he was six, is believed to have left the jihadi group after becoming fearful he might be killed by Islamic State's heads, reports the Daily Mail.

According to reports, the terrorist is scared that the publicity surrounding him, and his true identity being made public, make him a target for other Islamic State killers, who he thinks are conspiring against him.

IS would drop him “like a stone or worse if they feel he is no longer of any use to them,” a source told the Daily Express. “So it is possible he will end up suffering the same fate as his victims.” He is currently in Libya, according to reports, where he has joined a lesser-known terrorist outfit to keep "out of the limelight."

The 26-year-old, whose first Islamic State video appearance was in August 2014, usually has a black cloth covering his entire face, with only his eyes peeking through. But his real identity was unmasked by The Washington Post in February, a development that reportedly spurred Mohammad Emwazi to flee.

The former face of the Islamic State is wanted for the horrific murders of journalists and aid workers Stephen Sotloff, James Foley, David Haines, Alan Henning and Peter Kassig.

However according to Nick Kaderbhai, research fellow at the ICSR who told the Daily Mail that, Jihadi John's disappearance from the endless IS propaganda video may indicate that IS have 'nothing high profile to show off,' and not to take reports of his fleeing too seriously.

It recently came to light that the Tunisia beach gunman, Seifeddine Rezgui, also allegedly trained at the same terror camp as Emwazi.
