Five tourists have been attacked by sharks (with one killed) over the past week in the waters off Egypt's Red Sea coast, a vacation area especially popular with snorkelers and scuba divers. And nobody knows what to do.

Despite the frequent depiction of the cartilaginous fish as terrifying man eaters, these kinds of attacks are actually very rare. The Egyptian government has brought in experts from around the world to help solve the shark crisis. So far no one has arrived at a definitive conclusion, but possible explanations include over fishing in the Red Sea, an excess of resorts along the coast, and the effects of climate change.

There's another theory floating around, though: Israel's infamous intelligence agency is behind the attacks. Ahram Online reports (and refutes):

Speaking on the public TV program "Egypt Today" yesterday, a specialist introduced as "Captain Mustafa Ismael, a famous diver in Sharm El Sheikh," said that the sharks involved in the attack are ocean sharks and do not live in Egypt's waters.

When asked by the anchor how the shark entered Sharm El Sheikh waters, he burst out, "no, who let them in."

Urged to elaborate, Ismael said that he recently got a call from an Israeli diver in Eilat telling him that they captured a small shark with a GPS planted in its back, implying that the sharks were monitored to attack in Egypt's waters only.

"Why would these sharks travel 4000 km and not have any accidents until it entered Sinai?" said Ismael.

Earlier today, General Abdel Fadeel Shosha, the governor of South Sinai, backed Ismael's theory. In a phone call to the TV program, he said that it is possible that Israeli intelligence, Mossad, is behind the incident and that they are doing it to undermine the Egyptian tourism industry. He added that Egypt needs time to investigate the theory.

The shark attacks have the potential to do some real damage to Egypt, where tourism is pillar of the economy and an important provider of jobs. But the idea that Israel (which is currently dealing with its own Nature Channel-worthy crisis) is behind the attacks is pretty farfetched.
