Just a day before Americans elect a new president, anti-US protests have taken place in the Iranian capital.
The demonstrators have marked the anniversary of the 1979 seizure of the US embassy in Tehran.
Many have told reporters they do not think a changing of the guard in Washington will alter their views. But others say they do wonder if the election could lead to improved ties.
Thousands of students scaled the wall of the US embassy on November 4, 1979, and then held 52 Americans hostage for 444 days.
Iran has been a focus of the foreign policy debate during the campaign, with both candidates saying they will toughen sanctions over the nuclear question. Barack Obama, however, has said he could be willing to engage in direct talks if the conditions were right.
