The ISIS member dubbed Jihadi John, who is believed to be responsible for the beheading of American journalist James Foley and others, is also believed to be the man wielding a knife in the video threatening the lives of two Japanese men.

Jihadi John Is Back

In the video, Jihadi John puts pressure on the Japanese government to fork over $200 million to ISIS – the amount the country pledged to Middle East nations suffering from ISIS’s rampage – or else see their two country men killed.

“You now have 72 hours to pressure your government in making a wise decision, by paying the $200 million to save the lives of your citizens,” the man, clad all in black, warns. “Otherwise, this knife will become your nightmare.”

Japan has been trying to free the captives – freelance journalist Kenji Goto and self-employed contractor Haruna Yukawa – through communication with a third party and ISIS. The goal is to show ISIS that the money the country has pledged is purely humanitarian, not military, reported Yahoo. It’s unknown if Japan has made any progress in the alleged talks.

Why Is Jihadi John Still At Large?

Though it’s been rumored in the media that Jihadi John is British rapper Abdel-Majed Abdel Bary, whose stage name was L. Jinny, no official ID has been made public. Intelligence experts say that those working on tracking down Jihadi John likely believe it advantageous to keep the identity a secret.

“They can put pressure on his family, put pressure on his friends,” former CIA officer Aki Peritz told CNN. “Maybe they have a line to him. Maybe they know who his cousins are who are going to Syria who can identify him. However, if you publicly tell everybody who he is, his real identity, then maybe he’ll go to ground and he’ll disappear.”

Even if Jihadi John’s location were to be pinpointed, U.S. special operations would still likely have trouble actually spotting him.

“ISIS operates in what we call denied territory,” Cedric Leighton, a retired U.S. Air Force colonel, told CNN. “And that means by definition, that it’s very hard for our folks to get in there, it’s very hard for them to actually lay eyes on target.”
