A surfer was killed by a shark in France—the second fatal attack of this year.
The shark attacked the 28-year-old man off Reunion Island in the Indian Ocean.
It's the 24th attack since 2011 on the island and the 11th to result in death.
The shark was identified as a bull shark.
The attack prompted a 72-hour targeted fishing operation to try to catch some of the sharks in the area, the government said.
Researchers studying the significant increase in shark activity around Reunion Island concluded last year that the natural behavior of sharks in the Indian Ocean is part of the problem and that the development of the island's west coast was also a factor.
There was a twenty-threefold jump in shark bites off the island since the 1980s, the researchers said. Some 90 percent of the bites occurred during the peak months of June, July, and August along a 31-mile stretch along the island's west coast in the evening hours and on weekends.
"This is totally related to the sharks' behavior, and sharks preferentially attacked isolated swimmers and surfers," said Kiszka. "At dusk and dawn—especially at dusk—they tend to forage closer to shore."
The bull sharks usually stayed on the eastern side of the island but the development of the west coast has created more fresh water flows close to shore, luring them westward.
The first attack also happened off the French island.
He left behind a wife and 4-year-old daughter.
The shark "tore his leg off less than five meters from the shore," the outlet reported. He died a few minutes after being attacked.
