MINNEAPOLIS (WCCO/AP) — At least four children have been taken to the hospital following a school bus crash involving a pickup truck Thursday morning.

Sheriff Mark Empting said the crash happened at about 7:30 a.m. in rural Clay County. Empting said the preliminary investigation shows the driver of the pickup truck may have failed to yield, but the investigation is ongoing. The school bus was equipped with a camera, which will be used in the investigation.

According to Valley News Live, the bus was believed to be with the Ada-Borup Public School District. Empting said the students were of “all ages” and he did not have an exact number of students on board, but estimated there may have been 10.

Empting said deputies arrived to find the school bus driver rendering aid to the injured students. Four were taken to a hospital in Fargo with non-life threatening injuries. The driver of the pickup truck was also taken to a Fargo hospital; the bus driver did not appear to be injured, Empting said.
