Parade of G-20 protesters, police clash in Pittsburgh

PITTSBURGH — Police fired canisters of pepper spray and smoke and rubber bullets at marchers protesting the Group of 20 summit Thursday after anarchists responded to calls to disperse by rolling trash bins, throwing rocks and breaking windows.

Pittsburgh Police Chief Nate Harper said 17 to 19 protesters were arrested, and Mayor Luke Ravenstahl said swift police decisions resulted in minimal property damage. Officials said there were no reports of injuries.

The afternoon march turned chaotic at just about the time that President Barack Obama and first lady Michelle Obama arrived for a meeting with leaders of the world's major economies.

The clashes began after several hundred protesters, many advocating against capitalism, tried to march from an outlying neighborhood toward the convention center where the summit is being held.

The protesters clogged streets, banged on drums and chanted "Ain't no power like the power of the people, 'cause the power of the people don't stop."

The marchers included small groups of self-described anarchists, some wearing dark clothes and bandanas and carrying black flags. Others wore helmets and safety goggles.

One banner read, "No borders, no banks," another, "No hope in capitalism." A few minutes into the march, protesters unfurled a large banner reading "NO BAILOUT NO CAPITALISM" with an encircled "A," a recognized sign of anarchists.

The marchers did not have a permit and, after a few blocks, police declared it an unlawful assembly. They played an announcement over a loudspeaker ordering people to leave and then police in riot gear moved in to break it up. Authorities also used a crowd-control device that emits a deafening siren-like noise, making it uncomfortable for protesters to remain in the streets.

Protesters split into smaller groups. Some rolled large metal trash bins toward police, and a man in a black hooded sweat shirt threw rocks at a police car, breaking the front windshield. Protesters broke 10 windows in a few businesses, including a bank branch, a Boston Market restaurant and a BMW dealership, police said.

Officers fired canisters of pepper spray and smoke at the protesters, set off a flash-bang grenade and fired rubber bullets. Some of those exposed to the pepper spray coughed and complained that their eyes were watering and stinging.

About an hour after the clashes started, the police and protesters were at a standoff. Police sealed off main thoroughfares to downtown.
