A tragic end for a British aid worker in war-torn Syria.
ISIS released a video, yesterday, showing the murder of David Haines.
Footage shows an ISIS fighter beheading the 44-year-old hostage, who was helping struggling civilians at a refugee camp.
The video goes on to deliver a stark message to British Prime Minister David Cameron, with the terrorist group threatening to kill yet another of its captives, identified as British citizen Alan Henning.
Major news outlets are reporting Prime Minister Stephen Harper has joined Cameron in condemning the apparent killing. (File Photo)
