NEW YORK, April 29 (Xinhua) -- Thousands of workers and union members, who were angry over lost jobs and the taxpayer-funded bailout of banks, marched on Wall Street on Thursday.

This comes at a time when the U.S. Senate is set to open debate on a financial reform bill, after Republicans agreed on Wednesday to stop blocking the measure from reaching the Senate floor.

Protesters demanded that big banks be held accountable for their role in the financial crisis.

People at the rally called for new regulations to be enacted against Wall Street banks, and blamed the banks for triggering the recession.

The protesters, including people hurt by the mortgage crisis, held up signs saying "Wall Street Overdrafted Our Economy" and " Reclaim America."

Earlier, some 100 people entered a building housing JPMorgan Chase offices. They handed a letter to a building worker and chanted "Bust up big banks!" and "People power!"

The protesters then walked a few blocks and crowded into a Wells Fargo and Wachovia building lobby. But a Wachovia spokesman said the company did not receive a letter.
