The Occupy Wall Street movement has attempted to breathe new life into its campaign against inequities in the global financial system with a series of May Day protests across around the US.
Thousands of people turned out in New York for a day of action that culminated in a confident march down Broadway in the evening sunshine towards Wall Street, the crucible of the protest that began last year with an angry backlash against banking excess.

There were some clashes with police as officers clamped down on perceived violations, resulting in over 50 arrests. There were also flashpoints at protests in other cities.

Three letters were received on Tuesday: two at News Corporation headquarters and addressed to the Wall Street Journal and Fox News, and one at Citigroup. The message in the letters said: "Happy May Day".
