Britain reacted with horror on Saturday to the beheading of hostage Alan Henning, who many had dared to hope might be spared after a cross-community appeal for his release. Prime Minister David Cameron led tributes to the 47-year-old taxi driver who went to the region as a volunteer to deliver aid and whose death was announced by Islamic State jihadists in a video released late Friday.
