The mother of murdered soldier Lee Rigby, who was hacked to death in the street last year by Islamist fanatics, "wept" when she saw the news about the beheading of US journalist James Foley.
Lyn Rigby told the Sun on Sunday (£) that the American's violent death brought back nightmarish memories of her son's killing.
She said: "The moment I saw the news about James's beheading, I felt my heart turn over and I just wept."
She added that she supported calls from Foley's parents not to watch the fanatics' video, saying: "By refusing to watch, you are making a stand against the terrorists who are trying to push a nasty and violent agenda."
Fusilier Rigby, a 25-year-old father-of-one, was knocked down by a car near Woolwich Barracks in south east London and subjected to a frenzied knife attack in broad daylight. Michael Adebolajo and fellow extremist Michael Adebowale were this year convicted of his murder.
