New York ? A school bus overturned on a Bronx expressway Friday, injuring dozens of children and adults returning from a teacher’s funeral, authorities said.

The bus flipped on its side when another vehicle that was trying to merge onto the highway slammed into the back end of the bus about 11:15 a.m., police said. The bus was carrying seventh-graders, parents and faculty from St. Joseph’s Elementary School at the time.

“We tilted to the left, and then back, and then went over on the right and landed,” said Adesuwa Abulu, 12, who was sitting on the bus with a friend. “There were sparks everywhere. Kids were yelling, ‘Make it stop! Make it stop!”‘

The Archdiocese of New York said 42 students were injured, along with 10 faculty members and parents. Both drivers also were injured.

A total of 36 students and one teacher were treated for minor injuries at three Bronx hospitals, while the rest were aided at the crash site.

All the children were wearing seat belts, said Fire Chief Thomas Dunne.
