ISIS militants confirmed that the most celebrated executioner known as "Jihagi John" is dead.

In the eulogy written on page 23 of "Dabiq," the group's magazine, ISIS detailed Emwazi's death and confirmed the U.S. version of the events.

According to BBC News, "Jihadi John" was killed on Nov. 12 when the car he was in was struck by an unmanned drone in the city of Raqqa, the capital of the Islamic State's self-proclaimed caliphate in northern Syria. The airstrike destroyed the car and killed him instantly.

The eulogy also included a smiling picture of the militant, who the Islamic State militants described as an "honorable brother."

During the airstrike in November, a U.S. defense official said that one British and two American drones were involved. But it was one of the American drones that fired a Hellfire missile that hit the car. It was also believed that there was one other person inside the vehicle.

"He walked out of a building and got in the car. We struck it right after with zero collateral damage," a counter-terrorism official told ABC News last year. "The vehicle was on fire. It was a 100 percent flawless, direct hit."

The official added that "Jihadi John" "evaporated" in the explosion.

Aside from his death, the ISIS militants also described Emwazi's "harshness" towards the disbelievers of the caliphate.

"His harshness towards the kuffar (disbelievers) was manifested through deeds that enraged all the nations, religions, and factions of kufr, the entire world bearing witness to this," the "Dabiq" article said, as per Washington Post.

Meanwhile, Shirley Sotloff, the mother of one of the beheading victims of the Islamic State militants said on Tuesday that she's glad that the notorious executioner is finally dead. Kassig family's spokeswoman Jodi Perras said they had no comment about the news on Emwazi's death.

"It's good," Sotloff said, Fox News quoted. "I'm glad that he's gone, but it doesn't bring back my son."

Emwazi became known through his appearances in the ISIS' beheading videos of British aid workers David Haines and Alan Henning, U.S. journalist Steven Sotloff, American aid worker Peter Kassig, American journalist James Foley and Japanese journalist Kenji Koto, Newsweek noted.

He was also known as "Sheik of Slaughter." It was also believed that the Paris attacks last year were the militants' way to avenge his death, which was a significant blow to the terrorists.

Since Emwazi or "Jihadi John" is already dead, a new masked militant has replaced him in a recent execution video released by the group, USA Today has learned.

The confirmation of the death of Mohammed Emwazi, a Kuwaiti-born British militant also known as Abu Muharib al-Muhajir, came Tuesday, Jan. 19, after the Pentagon confidently announced that they could have killed ISIS' "Jihadi John" when a U.S. drone strike had hit the intended target in Raqqa, Syria in November 2015.
