The Mayor of New York has defended the decision to clear out the Occupy Wall Street camp saying it had become a health and safety concern.

More than 70 people were arrested when police moved in with tear gas and bulldozers at Zuccotti Park.

Meanwhile, The City of London Corporation has relaunched legal action against protesters
camped outside St Paul's Cathedral.

They had previously offered to give the group until the new year to leave the
site - but as the demonstrators rejected this offer - the Corporation feels
court is the only option left.
