An eight-man squad went behind enemy lines in Raqqa, Syria, earlier this month and posed as ISIS wives before taking out a high-value target.

The Express reported Monday that ISIS terrorists were utterly confused when special operations forces threw off burqas and opened fire. A U.S. Reaper drone assisted the troops with a well-placed Hellfire missile.

Local anti-ISIS forces helped transport the elite troops to an extraction site occupied by U.S. Air Force AWAC mission control aircraft.

"Gunmen were on the streets stopping everyone, lining people up against the walls and threatening to kill anyone who had helped the 'spies,'" a source told the Daily Star on Sunday.

Sources told the Express to expect such missions to occur with increasing frequency in the days ahead.

"Their primary target is the individual who has been dubbed the new Jihadi John," an intelligence source said. "He is at the top of the kill list."

Siddhartha Dhar, also known as Abu Rumaysah, left London in September 2014 after he was released on bail for encouraging terrorism.

"What a shoddy security system Britain must have to allow me to breeze through Europe to [ISIS]," he tweeted after catching a flight to Paris, BBC reported Jan. 4.

Rumaysah became the new "Jihadi John" after ISIS propagandist Mohammed Emwazi was killed in a coalition drone strike in Raqqa last November.
