At least five people were killed and more than 40 were injured when an SUV plowed into a Christmas parade Sunday in Waukesha, Wisconsin, city officials said.

Crowds were bundled up along Waukesha's Main Street to enjoy the parade when a red SUV drove through a series of barricades and barreled onto the parade route around 4:39 p.m. local time, Waukesha Police Chief Daniel Thompson said.

Roads in the area will remain closed for at least 24 hours, Thompson added. Businesses along road where the incident took place should remain closed Monday, city officials said.
