A total of 32 children were injured as the school bus they were travelling in overturned on Tuesday, police reported. The bus crashed in the mining city of Krugersdorp in the province of Gauteng. Eight children suffered moderate injures and the others slightly injured. The driver was also injured. The cause of the accident remains unclear. In the recent years, road accidents have become one of the biggest killers in South Africa. On June 25, 2012, a bus with 70 passengers plummeted off a bridge in the same province, killing at least 19 people and injuring dozens of others.
