LOS ANGELES (AP) - Los Angeles police have closed off streets surrounding the Occupy Los Angeles encampment.
Police cars line a one-block perimeter around the City Hall camp Tuesday night where hundreds of protesters are preparing for what they believe is an imminent raid by police.
Meanwhile, Occupy protesters in Philadelphia have begun marching through the streets after police ordered them from their tent encampment near city hall.
Some protesters in Los Angeles shot off fireworks near the camp where Occupy members discussed emergency preparations.
About half of some 500 tents remained after a Monday morning eviction deadline and the remaining protesters showed no sign of leaving the Los Angeles encampment, which is one of the largest still remaining in the country.
