Three other children were taken to a nearby hospital but most others from the classroom sustained minor injuries and were assessed at the scene, paramedics said.

Mariam Issmail, a fourth-grade student, was in a classroom nearby and said everyone in the class was very scared.
"We were just doing our work and all of a sudden we just heard this big bang," she said.
"We were crying. Kids were screaming and saying I want my mum, I want people, I want help. We had to stay in the classroom and stay until our parents came," she added.
Acting Assistant Commissioner Stuart Smith said they did not believe the incident was intentional.

"We're not looking this as an intentional act. It is a crash investigation," he said.
New South Wales Ambulance Superintendent Stephanie Radnidge said ambulance officers arrived to "a scene of carnage".
"[There were] a number of distressed and overwhelmed children and teachers at the scene of a horrible accident. Obviously they were crying, they were distressed, some were asking for their parents, that's a natural response to such a terrible set of circumstances,” she told The Sydney Morning Herald.
"It is very, very hard because we are parents ourselves, we are human beings,” she added.
