A little Red Sea story from DIVE magazine :-
Egyptian officials said the search is continuing for the four divers who went missing following a dive near the Red Sea resort of Marsa Alam on Saturday morning. Two Russians, a Dutch diver and their Egyptian dive guide became separated from the boat during a dive 13km north of Marsa Alam, according to reports.
The Red Sea Association for Diving and Watersports said it remained optimistic that the divers would be found. Dozens of boats, including navy vessels and helicopters are assisting in the search. The water temperature in the southern resort at this time of year is between 21 and 23ºC.
