OAKLAND, Calif. - Occupy Wall Street supporters who staged rallies that shut down the nation's fifth-busiest port during a day of protests condemned on Thursday the demonstrators who clashed with police in the latest flare-up of violence in Oakland, Calif.
Riot police arrested dozens of protesters in the city's downtown, where bands of demonstrators threw chunks of concrete and metal pipes as well as lit roman candles and firebombs, police said. At least four protesters and several officers were injured.
"I think it will allow detractors to criticize the movement," protester Hale Nicholson said.
The protest outside the Port of Oakland, which reopened Thursday, represented an escalation in tactics as a movement that had largely been about marches, rallies and tent camps targeted a major symbol of the nation's commerce.
The violence that followed, however, raised questions about the direction of the movement and whether the clashes, so far mostly isolated in a city with a history of tensions between residents and police, will galvanize protesters or hurt their cause.
Nicholson blamed the violence on a small group of young people just there for violence — "Some kids looking to blow off some steam."
In Los Angeles, a spokesman for the encampment there, said those demonstrators don't represent the movement.
