Sharks are attacking in the Florida coast

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 has occurred in 2005.
