A third innocent Westerner has been killed by the terrorist group ISIS.
British aid worker David Haines was filmed in a propaganda-type video showing his execution by a militant.
The video is consistent with two
videos of Americans killed by the same group.
Last month, US journalists James Foley and Steven Sotloff received the same fate.
David Cameron said of the murder of the father of two daughters:
“It was an act of pure evil. This is a despicable and appalling murder of an innocent aid worker. It is an act of pure evil.”
“My heart goes out to the family of David Haines who have shown extraordinary courage and fortitude throughout this ordeal.”
“We will do everything in our power to hunt down these murderers and ensure they face justice, however long it takes.”
