The father of a British man, previously thought to be one of the unmasked Isis killers featured in a propaganda film showing the killing of American aid worker Peter Kassig, has said the man in the video is not his son.
Ahmed Muthana, told The Times: "I looked at the line-up and I didn't recognise my son. One of them looked like him but the eyes and nose are different."
Video analysis commissioned by the paper also suggested that when compared to previous photos of student Nasser Muthana the man in the video did not appear to be the same person.
The father of the 20-year-old British man, Nasser Muthana, thought to feature in the latest Isis beheading video, has said his son should be executed if indeed it is him in the footage.
Speaking to Good Morning Britain's Chief Correspondent Richard Gaisford, he said he is shocked and appalled by the footage.
Ahmed Muthana tells me he has "closed the book" on his two sons since they went to Syria to fight with #ISIS .
Ahmed Muthana confirms he has seen images from latest #ISIS video. Can't be sure, but says he believes one foreign fighter is his son Nasser
Ahmed Muthana tells me if his son Nasser has beheaded anyone in Syria he too should be executed. He is shocked and appalled by his actions.
The father of British man Nasser Muthana said one of the unmasked Isis killers featured in the latest propaganda film showing the beheading of an American aid worker "looks like" his son.
Peter Kassig, known as Abdul-Rahman, was taken hostage in Syria in October 2013. Distressing video footage showing his apparent death appeared on social media over the weekend. His family said they are heartbroken to learn the news of his death.
Nasser Muthana, 20, from Cardiff featured on a Islamic State video last summer. He features as part of a line-up of fighters in the latest beheading video, but is not shown killing Kassig.
Speaking to the Daily Mail, Nasser's father said:
I cannot be certain but it looks like my son. He must be mentally ill - either that or there is something else not right.
Mr Muthana's other son Aseel is also thought to be in Syria.
Tonight on ITV former Wales rugby captain Eddie Butler undertakes a personal TV journey to discover the stories of thirteen Welsh Internationals killed on the battlefields of Western Europe during the Great War.
In Rugby At War, a special co-production between ITV Wales and the Welsh Rugby Union commemorating the centenary of the start of the conflict, Eddie pays tribute to the pivotal roles undertaken by this band of fallen Welsh rugby players. They came from diverse backgrounds, from across Wales, but all were united by their love of the game and their courage in the face of war.
The most famous of the group was former Wales rugby skipper Captain Johnnie Williams, who scored an incredible 17 tries in 17 games. He died at Mametz Wood, one of the bloodiest and most devastating battles of the First World War where Welsh casualties alone numbered some 4,000.
Eddie travels to the now peaceful French countryside to see for himself where his predecessor rugby Welsh captain fell, and searches for his grave among the vast sea of white headstones in the Corbie Communal Cemetery.
