Prosecutors revealed on Tuesday that a sixth person has died following a vehicle attack in which an SUV was deliberately driven into a weekend Christmas parade in Waukesha, Wisconsin in the United States. 

The death toll rose after an 8-year-old boy died, marking the first death of a child in the incident.

Darrell Brooks, 39, was charged with five counts of intentional homicide, and now faces a sixth murder charge, prosecutor Susan Opper said.
