A bus carrying British tourists has crashed on a notorious mountain road in northeast South Africa, klling two 19-year-old women. The tragedy, on the eve of the continent's first World Cup, also left 21 people injured. Although the tourists, thought to be from the London area, did not appear to be in the country for the football tournament as they had tickets to leave by air on Friday. Provincial police spokesman Leonard Shlati said: "The bus overturned on a windy road at a bend." One critically injured passenger was rushed by ambulance to hospital in Nelspruit, a World Cup host city 400 km east of Johannesburg. The accident occurred at about 0830 GMT, near the town of Barberton, police said. South Africa's roads, especially in the mountainous areas along its northeastern borders with Mozambique and Swaziland, are notorious for accidents. World Cup organisers identified transport as one of the tournament's major challenges.
