Alan Henning's brother Reg has urged Moazzam Begg to make similar efforts to save the lives of other hostages held by Islamic State (IS) militants, including British photojournalist John Cantlie and US aid worker Peter Kassig.
Reg Henning told the BBC:
If possible I would have liked anyone to have saved Alan's life, regardless of their history or background.
If Moazzam Begg believes he could have saved my brother's life I would ask him to make the same efforts to save the lives of all hostages in Syria including John Cantlie and Peter Kassig.
Colin Livesey says he "always thought his brother would be coming home" and his death means he no longer believes in hope.
Those that knew Alan Henning are in a state of shock at the brutal end to his aid mission to Syria.
