SHARM EL-SHEIKH (Egypt ) - A top Egyptian official has announced the opening of a kilometer-long section of beach at a Red Sea resort that has been plagued by shark attacks. South Sinai Governor Mohammed Shousha announced in a statement Thursday that the area reopened to swimmers and snorkelers was on the opposite end of Sharm El-Sheikh resort from where the shark attacks occurred. Last week, four tourists were mauled and one woman killed in series of unprecedented attacks believed to be carried out by a Mako and an Oceanic White Tip shark, prompting an indefinite closure of the waters to swimmers. One Mako shark was caught, but the other remains at large. Teams of local and US experts are trying to determine the cause of the sharks' unusual behavior.
