A bus carrying Mexican tourists overturned Friday in Egypt's Sinai Peninsula before bursting into flames, killing at least six tourists, according to the state news agency MENA. According to AP, Head of emergency services for South Sinai governorate, Khaled Abou Hashem, said the bus was carrying Mexican tourists from the peninsula's Saint Catherine's monastery to the Red Sea resort of Dahab. The accident occurred because of high-speed driving, a security official said, speaking on condition of anonymity because he was not authorized to talk to the media. MENA said 25 people were injured in the accident. Mexico's deputy foreign minister, Carlos de Icaza, told The Associated Press that the authorities were still working to confirm details of the accident. He said consular officials were on their way to the scene of the accident and that they were still not sure whether all of the victims were Mexican citizens.
