(?Gurney5) (Newser) – Yet another swimmer has been killed by a shark on a South Africa beach considered the most dangerous in the world. The victim this time was a 25-year-old swimmer who was standing up to his waist in water at a beach in Port St. John's. The shark nearly severed an arm and slashed the swimmer's chest and stomach. The man was hauled to the shore by lifeguards but died on the scene, reports the Telegraph. He was the sixth fatality from a shark attack off the same beach in six years.
