After a survey by a group of international experts, the beaches at Sharm el-Sheikh are to reopen, but only after strict new safety measures are in place. There will be continuous patrols by boats close to shore.
Watch towers are being established along the beaches, manned by professional divers, equipped with binoculars to scan for any sign of sharks. Swimmers will have to remain within designated areas, and rules against feeding sharks or any other sea life are being reinforced.
The international shark experts concluded that recent attacks were carried out by more than one shark, so waiting until the culprit was caught seems not to have been an option before opening the beaches, especially as the peak Christmas season approaches. But tourists may be understandably nervous and at least some cancellations are reported.
