Seizure of the US Embassy in Tehran

In February 1979, Ayatollah Khomeini returned from exile to Iran in the defining moment of a revolution that would change his country and the whole Middle East. In a special edition of the programme, Rebecca Kesby hears eye-witness accounts from the protestors who brought down the Shah, one of the Ayatollah's aides and an American embassy official taken hostage by Khomeini supporters. She also talks to the BBC Persian Service's special correspondent, Kasra Naji.
