a shark attacked some swimmers last week of the coast. 3 people are in the hospital in Kairo( missing alot of body parts), 2 days later they claimed they caught the shark and everbody jumped in again. It turned out, it was the wrong one and a german tourist got killed the next day of the beach from the hyatt ( I think she was on a free night ) They are still searching for the right shark. Its known that Sharm has Sharks, but not from the "i like human flesh for lunch" ones. So one guy got lost.
I dont know if you would enjoy your dive, looking over your shoulders every 10 sec.
Enjoy Dahab, its really nice. If you cant go swimming, take a trip to Sharm or visit St. Katarina in the mountains....
