New York City Police officers assemble at the intersection of Wall Street and Broad Street in front of the New York Stock Exchange, Thursday, Nov. 17, 2011. Two days after the encampment that sparked the global Occupy protest movement was cleared by authorities, demonstrators marched through New York's financial district Thursday and promised a national day of action with mass gatherings in other cities.

NEW YORK — Police in New York say they've arrested 50 to 60 Occupy Wall Street protesters at intersections near the New York Stock Exchange, brokerage houses and banks.

The protests are marking two months since the birth of the Occupy movement in a lower Manhattan park. Participants are opposing corporate excess and income inequality.

Protests are happening across the country Thursday.

About 500 protesters in Los Angeles are marching in the downtown financial district there.

In Albany, N.Y., protesters from Buffalo, Rochester and other encampments were coming in by bus to join a demonstration in a downtown park.

Police in Portland, Ore., closed a bridge in preparation for a march there.
