Hostage-takers
At 11.30am on 30 April 1980, six armed members of the Democratic Revolutionary Front for the Liberation of Arabistan (DRFLA) stormed the Iranian Embassy on Princes Gate in South Kensington, London, taking 26 people hostage.
The DRFLA had been involved in an Arab uprising in the southern Iranian province of Khuzestan following the Iranian Revolution of 1979. The group was still fighting for that region’s autonomy and seeking the release of prisoners captured during the rebellion.
Six days of tense dialogue with the Metropolitan Police negotiators began. The operation was directed by a team comprising the Metropolitan Police Deputy Assistant Commissioner John Dellow, Home Office Assistant Secretary Hayden Phillips, and Lieutenant Colonel Michael Rose, commanding officer of the Special Air Service (SAS), the British Army's primary anti-terrorist unit.
Until that time, the SAS was almost completely unknown to the general British public. But that was about to change.

Aiding the civil power
The involvement of the SAS in domestic law enforcement was something of a last resort. It only took place after the Home Office had formally requested support for the police from the Ministry of Defence.
During the 1980 siege, the regiment operated under close government supervision via the Cabinet Office Briefing Room A (COBRA), Britain's crisis management command. It also worked in full partnership with the police.
Once the operation was over, the police assumed full authority over the crime scene. Indeed, after the 1980 siege, several SAS soldiers involved were interviewed and questioned by detectives in order to establish that the force used was lawful.
Co-operation
General Sir Peter de la Billière describes SAS-police co-operation and the political context of the 1980 siege. Interviewed in 2015.
Operation Nimrod
Although the terrorists released several sick hostages during the crisis, on Day 6 they killed a captive, believing their demands remained unmet. Following threats that they would shoot more, the British government ordered the SAS to carry out a rescue mission - codenamed Operation Nimrod.
On 5 May, multiple teams of SAS soldiers assaulted the building, one group in full view of the assembled press. In 17 minutes, after a fierce firefight, the siege was over and 19 hostages had been freed. All but one of the terrorists were killed.
The surviving gunman, Fowzi Nejad, was later convicted of conspiracy to murder, false imprisonment and two charges of manslaughter. He was released from prison in 2008 after completing his sentence.

7.24pm
With a colleague dangling from his ropes, the team at the rear ground floor cannot use their explosives. They instead smash their way in with sledgehammers.

At the front, another team crosses from an adjacent balcony and detonates frame charges against the armoured windows. They throw in stun grenades and enter the building, which is soon ablaze.
7.26pm
On the first floor, PC Lock wrestles with Salim, who is then shot by the SAS. Elsewhere in the building, one hostage is killed and two others injured in the firefight, before the terrorists are killed.
7.29pm
The SAS evacuate the hostages down a staircase, but another gunman - armed with a grenade - conceals himself amongst them. The SAS spot him, consider the threat he is posing to the hostages, and shoot him.
7.32pm
The hostages are led outside to lie down with hands bound. The last remaining gunman, Fowzi Nejad, is discovered hiding amongst them. He is quickly removed and arrested.
7.40pm
The assault ends. Control of the situation and area passes back to the police. Inside COBRA, there is cheering and great relief as a higher death toll was expected.
Standards of training
Corporal Robin Horsfall on the equipment, training and professionalism required to complete a successful operation. Interviewed in 2017.
'It is highly probable that those involved will receive awards for bravery as a result of Monday’s action. But there will be no citation… to have "beaten the clock" is satisfaction enough for the men of Britain’s most private army.'

Legendary status
The deadly efficiency of the rescue operation, some of which was played out on national television, contributed to the legendary status of the SAS. The images of daring soldiers dressed in black tactical clothing and gas masks became symbols of the prowess of British Special Forces.
The siege also awakened public interest in the Special Forces, its history and operations. This led to an explosion of newspaper articles, books, documentaries and films about the SAS, and other mysterious units, such as the Special Boat Service, that continues to this day.
