A 36-year-old diver was killed after lightning struck his oxygen tank, authorities said.

The man, whose name was not immediately released, was diving with three others off a boat near Deerfield Beach on Sunday.

When he surfaced, "lighting struck his tank," said Deerfield Beach fire Chief Gary Fernaays. "He was approximately 30 feet from the boat at the time."

The man was rushed to the beach where a rescue crew was waiting. He was given CPR and taken to North Broward Medical Center in Pompano Beach, where he was pronounced dead, Fernaays said.
