Three people were killed and 22 injured when a South African bus carrying teams of speed skaters from New Zealand, Italy and the Netherlands crashed on Monday, police said according to Reuters. Police spokeswoman Elsa Gerber said the accident occurred early on Monday on a national highway in the Free State province more than 500 km (300 miles) southwest of Johannesburg. "All the dead are South African, we are trying to reach their next of kin," another police officer said. Most of the passengers were speed skaters from New Zealand, Italy and the Netherlands on a tour of South Africa. The foreigners suffered injuries, Gerber said. South Africa's roads are among the most dangerous in the world and many foreign visitors have been killed on them in the past. In 1999, 27 elderly British tourists died when their bus ploughed off the road as it descended a mountain pass near the eastern highland town of Lydenburg.
