Police confront Oakland protesters with tear gas

Police fire stun grenades and tear gas at Occupy Oakland protesters who throw rocks and hurl canisters back in an overnight confrontation on the downtown streets.<br/> A fire lights up the scene where the anti-Wall Street demonstrators linger after a day when thousands rallying to protest economic inequality shut down the busy Port of Oakland but failed to bring the Northern California city to a halt.<br/> Hundreds of police in riot gear advance in a line and start making arrests. They estimate 60 people have been arrested.<br/> The authorities appear to be trying to force protesters from expanding their foothold around a public plaza.<br/> Oakland has become a national flashpoint for the Occupy Wall Street movement after a former Marine was badly injured in a violent clash with police last week.<br/> Katharine Jackson, Reuters.
