A man is missing after an extremely rare shark attack on Monday off the coast of northern Israel.
The attack was recorded in the sea in Hadera, about 40 kilometers north of Tel Aviv.
The incident was witnessed by people on Olga Beach, and on recordings on social networks you can see them screaming in shock.
Sharks are known to congregate where warm water is released by the local power plant, especially at this time of year, but they are usually harmless.
There have been no fatal shark attacks recorded in Israeli waters since the country's founding in 1948.
Police have closed the beach and are searching for the missing man.
