Seven children and one adult were injured when a semitrailer truck broadsided a school van near Benson, Minn., on Monday afternoon, authorities said.

“It’s very traumatic. ... It’s a horrific crash,” Swift County Sheriff John Holtz said. “And with children involved ... it really hits home.”

The Sheriff’s Office said everyone on the bus — its driver and seven children — was hurt. The children range from about 8 to 16 years old.

Holtz said the van was “T-boned” when it entered the intersection. “The van was coming off a gravel road crossing a tar road,” he said.

The Sheriff’s Office received the 911 call just before 4 p.m. about a two-vehicle crash on County Road 20 and County Road 63 NW in Danvers, Minn., which is west of St. Cloud.

Upon responding, deputies were told the crash involved a school van from Hancock, Minn., carrying seven children home from school and a semi.

First responders transported an adult driver of the van and the schoolchildren to two local hospitals, a news release said. At least two people were airlifted to hospitals in the Twin Cities, Holtz said at a news conference late Monday. The semi driver was not hurt, he added.

Hancock Superintendent Loren Hacker said school officials are working with authorities to help the students and the families.
