New York: Occupy Wall Street claimed victory after what it called a "historic day" of action which drew tens of thousands of protesters onto streets worldwide and breathed life into the embattled movement.
But the future of the OWS campaign denouncing growing social inequality, corporate greed and corruption remained in doubt after its symbolic New York epicenter was uprooted this week along with camps in other cities.
Organisers, citing unpublished New York Police Department figures, said some 32,500 people gathered on Thursday, the movement's two-month anniversary, at Foley Square in lower Manhattan before many marched across the Brooklyn Bridge.
That peaceful show of force followed a more raucous protest earlier in the day, when about 1,000 people tried to block access to the New York Stock Exchange in demonstrations leading to violent clashes which left seven policemen and 10 activists injured and more than 250 people arrested.
According to OWS, there were "actions in at least 30 cities across the country and around the world" including US protests in Los Angeles, Portland Oakland and Washington.
"I think it was a success, with the large number of people who were engaged," movement spokesman Bill Dobbs said referring to the New York protest.
The Occupy movement said on its website that after Tuesday's raid dismantled their New York camp in Zuccotti Park, "The slogan 'You can't evict an idea whose time has come' became the new theme of the 99 percent movement overnight.”
"The mobilisation today proved that the movement is on the ascent and is capable of navigating obstacles," the group said.
The protests won extensive media coverage, with most major New York papers and others around the country carrying images of the clashes on their front pages.
"I felt that this was a really important moment historically," Coral Zayas, a school teacher in Manhattan said on Thursday as she decried the growing US income gap and worsening conditions in many school districts.
"It's unacceptable that today, probably many people were down on Fifth Avenue buying USD 3,000 bags... and my kids don't have enough space to work in or a decent text book."
