PITTSBURGH — Protesters and police clashed Wednesday on the streets of Pittsburgh after police tried to break up a march opposing the Group of 20 summit.
Protesters rolled trash bins toward police, and a man in a black hooded sweatshirt threw rocks at a police car, breaking the front windshield. Some protesters also used pallets and corrugated steel to block a road.
Officers fired gas at the protesters. Some of those exposed to the gas were coughing, complaining of eyes watering and stinging.
The march began with several hundred protesters. It did not have a city permit, and police declared it an unlawful assembly. The group broke into smaller groups after being confronted by police.
