Six employees of HSBC Bank in the UK have been sacked after making a mock ISIS execution video during a team-building exercise at a go-karting venue.

In the video, five masked, black-clad bank workers brandish a coathanger and shout Allahu Akbar while a sixth man in an orange jumpsuit kneels at their feet. The video was posted on Instagram and quickly deleted, but not before it had been seen and shared.

The owner of the go-kart venue has condemned the video and says it was filmed without the knowledge of staff, in a changing room.
