A 38-year-old kiteboarder has died after being attacked by several sharks off the coast of Florida, near Stuart Beach.
Stephen Howard Schafer was kitesurfing in an unguarded water zone.
A lifeguard even tried to rescue the kiteboarder, but he was severely wounded and unconscious and died in the local hospital.
Authorities have closed a few beaches as they have been spotting hundreds of dangerous sharks by the Florida coast in the past weeks.
Schafer was an experienced kiteboarder. The last shark-bite fatality in Florida occurred in 2005.
