British Prime Minister David Cameron has condemned the Islamic State group as a “depraved organisation” after the extremists released a video claiming to show that militants have beheaded US aid worker Peter Kassig.
Cameron said that like others who have been “murdered in cold blood” by the group, Kassig was a selfless humanitarian worker who had gone to the region to help others. Cameron said the video “underlines the deplorable depths to which these terrorists are prepared to go — savagely murdering a compassionate man.”
