Videos of a man shooting himself repeatedly in the mouth with different guns, while remaining unharmed, have been viewed tens of thousands of times on Facebook. The man, who is wearing what appears to be a South Sudanese military uniform, boasts that he is able to protect the country’s President Salva Kiir thanks to this mysterious power. What’s behind the trick? AFP filmed a demonstration with a forensic ballistics expert to show that the man was firing blanks rather than live ammunition. Another firearms expert called the man’s behaviour “incredibly dangerous”, warning that children could be seriously hurt trying to copy him.
