Hundreds of demonstrators gathered on Saturday near Wall Street to protest against the financial system which they say brought the U.S. economy on the verge of crisis.
Activist magazine Adbusters, which announced the event in July, said some 20,000 people are expected to take part. So far, about 700-1,000 protestors arrived to the area.
Participants chant slogans about "financial terrorists" and "financial mass destruction." Some of them are carrying cardboard signs saying "represent the 99%."
Police units cordoned off the Wall Street and the Charging Bull statue where the protestors intended to gather.
"If the police block us temporarily from occupying Wall Street, then let's turn all of lower Manhattan into our Tahrir Square," the campaign's website reads. "...And if need be, let's set up our encampments in nearby Battery Park and other places until we're ready to walk into Wall Street again."
The protests were inspired by this year's uprisings in Egypt, Tunisia, Syria and other countries. They are orchestrated through Twitter, Facebook and other social media websites.
