A U.S. official says relations between the United States and Iran continue to be marked by deep "mistrust," after thousands of people took part in anti-American protests in Tehran.
Crowds of Iranians demonstrated outside the former U.S. Embassy in Tehran on November 4 to mark the anniversary of the 1979 takeover that ultimately cut diplomatic relations between Washington and Tehran.
Observers say the annual rally had greater significance this year because protesters were expressing opposition to attempts by new Iranian President Hassan Rohani to ease tensions with Western countries over Iran’s nuclear program.
U.S. State Department deputy spokeswoman Marie Harf said the huge turnout showed the depth of long-standing problems between the two countries.
"We've all been clear that this is tough, and that there's a deep history of mistrust here,” she said.
