A man has been killed by sharks while surfing off Florida's southern Atlantic coast

A lifeguard found Stephen Schafer, 38, surrounded by sharks about 500m out from shore

The lifeguard "saw blood in the water and heard the male screaming that a shark had bit him",

The lifeguard put Mr Schafer on his rescue board and paddled back to shore.

Mr Schafer was taken to hospital, where he later died.

While swimmers and surfers often receive minor bites in Florida, officials say fatal shark attacks are extremely rare.

The fatality is Florida's first shark bite death in five years
