The wife of a British taxi driver being held hostage by Islamic State has pleaded with the militants to "see it in their hearts" to release him.

Alan Henning, from Eccles in Salford, was seized while on an aid mission to Syria last December.

The militants issued a threat to kill the 47-year-old in a video released last Saturday which showed the killing of another British man, David Haines.
