A video purporting to show the beheading of British hostage Alan Henning has been released by Islamic State militants.
The Salford taxi driver was delivering aid to Syria in December when he was kidnapped then held hostage by IS.
IS had threatened to kill him in a video showing the killing of UK hostage David Haines released last month.
On Tuesday, Mr Henning's wife Barbara appealed for his release, saying: "He is innocent."
IS has previously released videos showing the apparent beheadings of two US journalists James Foley and Steven Sotloff, and Briton Mr Haines.
The video released on Friday is yet to be verified.
