Iranian protesters set a US flag on fire and step on a portrait of President Joe Biden, during a rally outside the former US embassy in the capital Tehran on November 4, 2021, to mark the 42th anniversary of the start of the Iran hostage crisis. In 1979, Washington cut diplomatic ties with Tehran after more than 50 embassy staff were taken hostage in the seizure of its mission by radical pro-Khomeini activists.
