Three foreigners and an Egyptian were missing Sunday after they went scuba diving in the Red Sea the day before, an Egyptian diving association said, according to The Associated Press. The Red Sea Association said one Egyptian guide, three Russians and a Dutch man began scuba diving Saturday morning north of Marsa Alam, located about 160 kilometers (100 miles) southeast of Cairo. The boat accompanying them first reported the divers missing several hours later when they did not return to the boat after being at sea. One of the Russians divers swam for several hours before reaching a village north of Marsa Alam and informed authorities that the other four divers were lost in an area with thick coral reef, the association said in a statement. The missing are Egyptian scuba diving guide Mahmoud Ahmed Hamdan, a Russian man, a Russian woman and a Dutch man, the Red Sea Association said. The Russian Foreign Ministry identified the Russian missing man as Dmitry Kapitonov and the woman as Yelena Sundukova. The diver who swam to shore, identified as Vladislav Lukyanchenko, said sharks appeared in the area where the team had been diving, the ministry said in a statement. The name of Dutch diver was not available, and the Dutch Embassy in Cairo said it did not have any details about him.
