A 7-year-old girl and a woman were killed and eight others were injured in Kameoka, Kyoto Prefecture, on Monday morning when a car driven by a teenager plowed into a group of mostly children as they were walking to a nearby elementary school, police said.

The 18-year-old driver, whose name has been withheld because he is a minor, was arrested on suspicion of negligent driving resulting in injuries. He apparently had no valid driver's license and was in the minicar with two friends at the time of the crash.

His friends, also 18, were arrested on suspicion of letting an unlicensed person drive.
