Four people were killed in a small Illinois town on Monday afternoon when a driver crashed a car through a building during an after-school program, local police said.

The incident, which saw the driver crash into three people before hitting a fourth person while smashing through the building, occurred at approximately 3:20 p.m. local time, according to the Associated Press. 

The first three fatalities occurred outside the building, while the fourth occurred indoors.

Other people were injured in the incident, but the number is not clear and they have been transported to local hospitals via ambulance and helicopter, according to the Springfield State Journal- Register. 

It was not immediately clear whether the incident was intentional, and no additional information about the victims have been released so far. But the driver, who was uninjured, has been taken to a hospital for evaluation, Chatham Police Department Deputy Chief Scott Tarter told reporters.
