IOWA CITY, Iowa -- The burning of a national symbol led to a confrontation in Iowa City Thursday afternoon.

WHO-TV reports a group of protesters were seen setting fire to the American flag along the pedestrian mall. People passing by confronted them, including someone who appeared to be a FedEx driver even pulling away one of the flags.

The video of the exchange comes from the Iowa Press-Citizen.

At one point the FedEx employee returns with a fire extinguisher, spraying it at the other protesters trying to light a flag on fire.
