British hostage Alan Henning 'killed by Islamic State'

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 the 47-year-old in a video showing the killing of Briton David Haines last month.
