Infamous Isis executioner Mohammed Emwazi, who was known as Jihadi John, was reportedly targeted in a US airstrike near Raqqa in Syria on Thursday. 

While several reports said that the Pentagon was still to confirm if Jihadi John was killed, ABC News has reported that the Isis executioner was 'eviscerated'.

The channel cited a US official saying the operation was "flawless" and a "clean hit".

"US forces conducted an airstrike in Raqqa, Syria, on 12 November 2015 targeting Mohamed Emwazi, also known as Jihadi John," the Pentagon press secretary Peter Cook said.

Jihadi John was allegedly responsible for several beheadings of Isis victims caught on gory videos circulated by the group over the past year. 

Some of Jihadi John's victims were  US journalists Steven Sotloff and James Foley, Japanese journalist Kenji Goto and several others. 

Emwazi was born in Kuwait but moved to the United Kingdom as a child. His British accent was evident in the chilling Isis videos that he appeared in, speaking in threatening messages before going on to behead his victims with a small knife. 

If Emwazi has indeed been killed, it will be a blow to 'Isis moral', jihad researcher Charlie Winter said on Twitter.
