The Iranian Embassy siege took place from 30 April to 5 May 1980, after a group of six armed men stormed the Iranian embassy on Prince's Gate in South Kensington, London. The gunmen, Iranian Arabs campaigning for sovereignty of Khuzestan Province, took 26 people hostage, including embassy staff, several visitors, and a police officer who had been guarding the embassy. They demanded the release of prisoners in Khuzestan and their own safe passage out of the United Kingdom.
