The Iowa State Patrol reports two children, ages 8 and 5, died in a single-vehicle crash late Tuesday morning just outside of Jamaica, in Dallas County. Four other people, including an 11-year old, suffered serious injuries. Only two of the victims were wearing their seat belts. No names had been released as of early this (Wednesday) morning.

Authorities say the accident happened as a 2014 Toyota Sienna driven by a 16-year old was traveling north on Beaumont Place at around 11:27-a.m., and was transitioning over a bridge, when the minivan suddenly veered left.

The vehicle moved left off the road before moving back to the right and leaving the road. It impacted the south side of a field drive, traveled over the drive, and came to rest upon the field drive, facing east. The accident remains under investigation.
