Two children are hospitalized with critical injuries after an S-U-V collided with a horse drawn buggy in Montcalm County.

The 13 and 10-year-old children, of Carson City, were taken to a downstate hospital.

The SUV driver and a five year old passenger were not hurt.

The horse suffered serious injuries and was euthanized.

The sheriff's office says bright morning sun may have been a factor in the crash.
