Emergency responders say least 20 children have been killed when their minibus collided with a truck northeast of South Africa's capital, Pretoria.
The children died after the vehicle burst into flames following a collision with a truck just north of the capital.There were understood to be both primary and secondary school-aged children on board. Panyaza Lesufi, the official responsible for education in Gauteng province, has said it is a "dark day".
The minibus collided with a truck on the single carriageway R25, between Verena in Mpumalanga and Bronkhorstspruit in Gauteng.
It is not yet known what the cause of the accident was, but pictures show the minibus entirely burnt out.
In a statement, emergency medical service ER24 described arriving at the scene, where fire-fighters were tackling the flames. A number of children had already been pulled out by "members of the community", the statement said. "Once the flames had been extinguished, paramedics found that approximately 13 children lying trapped inside the vehicle. Unfortunately, nothing could be done for the children and they were declared dead on the scene," the statement added.
The other children were found outside the vehicle.
ER24 and the Gauteng Education Department have since confirmed the number has risen to 20. "This is a huge loss and we're deeply pained by the tragic news," the education department tweeted.
South Africa has some of the deadliest roads in the world. According to the country's Road Traffic Management Corporation, there were 13,673 deaths in the 12 months from October 2015 - which equates to more than 37 people dying every day.
It was announced on Friday that road deaths over the long Easter weekend had jumped 50% compared to last year. Images posted by the ER24 medical service on Twitter show the minibus smoking and twisted.
