Iranian embassy in London 1980:

It is an assault on the British SAS (for some the best in the world) to free 26 hostages who had taken six armed men who demanded the restoration of the autonomy of the region of Khuzestan (mostly Arab).

In an operation of 17 minutes, the military released all hostages except one who died (one had been executed) and killed five kidnappers. After the slaughter of Munich and increasing violence in Northern Ireland, London had specialized part of the SAS in counterterrorism operations: Counter Revolutionary Warfare Wing.

Finally it was agreed that the British government would cover repairs to the Iranian embassy and the Iranian government for damage caused to the British Embassy during the Iranian Revolution last year.
