Six HSBC bank staff members in Birmingham, England were fired Tuesday after posting a video imitating an Islamic State execution, made during a staff day at a go-kart track.In the video, five men were shown standing above another man kneeling on the ground, wearing an orange jumpsuit. The men in the clip were shown holding coat hangers and saying "Allahu Akbar" while cheering. Islamic State terrorists are known for posting graphic videos of executions, especially beheadings, as they attempt to gain control over parts of the Middle East and impose their extreme style of Islam. According to British newspaper The Sun, the clip was originally posted to Instagram following a team-building day at Teamworks Karting track in Birmingham. It was later deleted after shocking co-workers and eventually the bank itself. An HSBC bank spokesperson explained the decision to immediately fire the employees, thought to be part of the bank's legal team, saying, “This is an abhorrent video and HSBC would like to apologize for any offense caused.”The bank has been in hot water since February when it admitted that its Swiss subsidiary helped wealthy clients dodge taxes and conceal millions of dollars of assets.Several British nationals have been abducted and killed by the terror group, including Alan Henning and David Haines, who wore orange jumpsuits as they were beheaded. The fate of British journalist John Cantlie remains unknown after he was kidnapped by Islamic state in 2012 and forced to make a number of Islamic State documentary-style videos.
