Jihadi John appeared in a number of videos in which hostages appeared to be beheaded. Here are the reactions of the families of the people he is believed to have killed.
The mother of Jihadi John’s first victim has said the news of his potential death gives no solace to her family.
Diane Foley, the mother of US journalist James Foley, said it “saddens” her that people were celebrating the killing of Mohammed Emwazi, who she said was a “deranged, pathetic, young man”.
James Foley, who was abducted in Syria in November 2012, was the first shown in what was to become a series of videos appearing to show beheadings. The footage, released in August, faded to black just as a knife was held to his neck by the man who would become known as Jihadi John.
When asked if the news of his potential death gave her solace, Mrs Foley told ABC: “No, not at all.
“Had the circumstances been different, Jim probably would have befriended him and tried to help him. It is just so sad that our precious resources have been concentrated to seek revenge or kill this man when if a bit of them had been utilised to save our young Americans, that’s what our country should be doing, I think – protecting our citizens and the people who are vulnerable, not trying to seek revenge and bomb.
“Jim would have been devastated with the whole thing. He was a peacemaker. He wanted to figure out why this was happening.”
The sister of the US journalist killed by Jihadi John said justice has “finally” been served.
But Lauren Sotloff, Steven Sotloff’s sister, also said a drone strike was not the death she would have wanted for Emwazi.
“Finally a bit of justice,” she wrote on Facebook. “Not the way I would of wanted him to die. He should of had his head cut off also and been left to suffer. But at least he is dead.
“Hoping my brother is in heaven knowing some justice was served. Unfortunately this does not change things. Wish they would have killed him while my brother was still alive. Its just too late [sic].”
Steven had been working in Libya and was writing about issues from the Middle East, particularly the Syrian civil war. He is believed to have been abducted close to the border with Turkey near the city of Aleppo
A statement released by his parents, Art and Shirley, read: “This development does not change anything for us; it’s too little too late. Our son is never coming back.
“More importantly, today, we remember Steven’s remarkable life, his contributions and those of James Foley, Abdul-Rahman Peter Kassig, Kayla Mueller, David Haines, Alan Henning, Kenji Goto, and everyone else who has suffered at the hands of Isis.”
The daughter of the British aid worker murdered by Jihadi John said she felt “an instant sense of relief” upon hearing the news of his potential death.
Bethany Haines, daughter of David Haines, told ITV News: “After seeing the news that Jihadi John was killed I felt an instant sense of relief, knowing he would not appear in any more horrific videos.
“He was only a pawn in Isis’s stupid game but knowing it is over and that he is finally dead still has not sunk in.
“As much as I wanted him dead I also wanted answers as to why he did it, why my dad, how did it make a difference?”
David Haines was shown in a video on September 13 last year. He had been held by Islamic State for 18 months after being captured during his first mission taking aid to Syrians caught up in conflict.
The former RAF engineer, who was born in Yorkshire but raised in Perth, first appeared in the background of a video in which US journalist Steve Sotloff was killed.
The brother of the taxi driver murdered by Jihadi John has said he is “glad” to hear the news of the killer’s potential death.
Reg Henning, the brother of Alan Henning, who died in October 2014, told ITV News: “Hopefully this is the end of it. I am glad he is dead.
“I would have preferred him to face justice. I think things will quieten down. If they had arrested him and gone to court, it would have dragged on for months and months.”
Alan Henning’s nephew, Stuart, tweeted: “Mixed feelings today wanted the coward behind the mask to suffer the way Alan and his friends did also glad it’s been destroyed [sic].”
Henning was kidnapped after going over the border from Turkey in December 2013 and held hostage by Isis for 10 months. He appeared to be killed in a video released on October 3 2014.
In footage from the Turkish border filmed shortly before his capture, Mr Henning spoke about his aid work. He said: “No sacrifice we do is nothing compared to what they are going through every day, on a daily basis.”
The mother of the Japanese journalist believed to have been killed by Jihadi John has said her son would have wanted to see the world free of conflict.
Junki Ishido, the mother of Kenji Goto, the 47-year-old journalist and film-maker who appeared in an apparent beheading video on January 31, told Japanese broadcaster NHK: “I only wish there will be no more conflicts like these in this world, as my son had hoped to see peace prevail around the world.”
Goto was captured by militants near Aleppo, Syria, in the summer of 2014.
He had travelled to Syria just three months after his second daughter was born. Before his last trip, he made a video recording in which he said he would always love the Syrian people “no matter what happens to me”.
His father Shoichi described him as kind and brave.
American Peter Kassig was captured in Syria in October 2013 while providing medical training and humanitarian aid to victims of the country’s conflict.
Footage showing his beheading emerged on November 16. He had taken the first name Abdul-Rahman after converting to Islam during captivity
During a memorial service after his death, Hazem Bata, executive director of the Islamic Society of North America said: “We’re here because of how he lived. We’re here because of the type of man he chose to be. We’re here because of his selflessness.”
