Greece has deployed thousands of police officers in Athens to prevent violence during an annual protest march Thursday.
The march to the U.S. embassy is expected to include demonstrators upset about the new interim government's austerity measures.
These demonstrations come a day after the government overwhelmingly won a vote of confidence in a parliamentary vote.
That vote supports efforts by new Prime Minister Lucas Papademos to impose unpopular spending cuts and tax increases.
