New York, Oct 4 (PTI): Large scale protests against corporate America spread across the country today with demonstrations being held outside federal banks and financial districts from Los Angeles to Boston.

The Occupy Wall Street protests entered their third week here with protesters dressed up as "corporate zombies" marching through Wall Street, the city's financial hub.

People used social networking sites Facebook and Twitter to spread their message and garner support for their cause.

Support groups like 'Occupy Boston', 'Occupy Philadelphia', 'Occupy Chicago' were also created online.

In a radio interview, New York Mayor Michael Bloomberg said the protests should not target Wall Street officials, "who make USD 40,000 or USD 50,000 a year and are struggling to make ends meet. That is the bottom line. Those are the people who work on Wall Street or in the finance sector."

In Manhattan, hundreds of people responded to calls from organisers and came dressed up as zombies, walking around the financial institutions clutching fake money.

They held up signs that read 'Down with the World Bank', 'How to fix the deficit: End the war, tax the rich,' 'End corporate personhood,' and 'Say no to corporate America.'

People have camped out on the streets, sleeping on sidewalks. Some supporters of the protests have distributed blankets, sleeping bags and food items to demonstrators.

In Chicago, people gathered outside the Federal Reserve Bank while protesters camped out near City Hall in Los Angeles.

Similar marches against corporate America, greed on the Wall Street and government bailouts to financial giants during the economic crisis were held in downtown Boston.

The protests, which began with a handful of people camping in front of the New York Stock Exchange on September 17, got a philip and nationwide attention after over 700 protestors were arrested over the weekend by the police as they tried cross the Brooklyn Bridge.

Similar rallies are being planned in places like St Louis, Kansas City, Hawaii, Tennessee, Minneapolis and Baltimore, according to 'Occupy Together', the unofficial hub for all events springing up across the country in solidarity with the Occupy Wall Street movement.
