CAIRO (AP) - A bus carrying Mexican tourists overturned on Friday in Egypt's Sinai Peninsula before bursting into flames, killing at least six, according to the state news agency Mena.

Head of emergency services for South Sinai governorate Khaled Abou Hashem said the bus was carrying 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 authorised to talk to the media.

Mena said another 25 people were injured in the accident.

Road accidents are common in Egypt due to badly maintained roads and poor enforcement of traffic laws. According to a 2012 World Health Organisation report, road accidents kill about 12,000 people each year in a population of about 90 million.
