A bus conveying over 100 students of the Ministry of Health Basic School crashed into a house at Exhibition in Dansoman, Thursday.
Scores of the children had cuts on their heads.
They were on their way for an excursion to the Kasoa Mall when the brake of the bus they were travelling in for an excursion failed.
"I was descending the hill when I lost control of the steering wheel. I didn't want to go down the main road because I might hit other cars or people," said the driver.
According to the driver, he had to run the bus into a nearby wall to reduce any chance of injuring many people.
The police have since towed the accident bus away from the scene.
