Professor Kazem Rajavi

The second was to plant a bomb in his car, connected to either the brakes or ignition, that would detonate once the speed reached 40kmh.

And the third plan was to assassinate him as he was commuting to or from home.

A budget for the operation was then approved at a meeting with new Iranian regime’s president Rafsanjani, Ali Khamenei, mullah Mohammad Hejazi, head of the special affairs committee, Falahian, the intelligence minister, foreign affairs minister Velayati, former intelligence minister Reyshari, and then IRGC chief Mohsen Rezaei.

On 30 August 1989, a first team headed by Akhondzadeh-basti and fellow henchman Saeed Hemati went to Geneva with diplomatic passports to review the plan. Based on their evaluation, the second plan for a car bomb was ruled out and they began working on only the first and third plans.

On 18 October 1989, a hit squad entered Geneva again and tried carry out the first plan of massacring Rajavi's whole family, but because Kazem was away on a trip, the plot was aborted.

On 31 January 1990, the second squad arrived in Geneva, but due to internal squabbling between the terrorists, that plan too was cancelled.

Then on 10 April 1990, six terrorists by flew to Geneva on Iran air. Mohammad-Ali Hadi Najaf Abadi, Iran's ambassador to the United Arab Emirates also went to Geneva eight days later using diplomatic passport number 006646 and stayed in room 625 of the Intercontinental Hotel.

Akhondzadeh-basti also flew to Geneva by Iran Air on 18 April, with air ticket number 096 4261 831174 and diplomatic passport number 006588, and stayed at the same hotel.

The two men oversaw the operation to kill 56-year-old Professor Rajavi, who was shot in his car as he drove home at 11.50am on 24 April, 1990.  Akhondzadeh-basti, Abadi and a number of other known terrorists returned to Tehran on an Iran Air Boeing 737 plane the same evening.

Professor was the elder brother of Iranian opposition leader Massoud Rajavi. He worked tirelessly to defend human rights in Iran and also held six doctorate degrees in the fields of law, political science, and sociology from the universities of Paris and Geneva.

After a lengthy investigation, Swiss justice and police officials and chief magistrate Roland Chatelain found that 13 Iranian agents had used 'service passports' to enter Switzerland to kill Professor Rajavi and confirmed the role of Iranian regime under Akbar Hashemi Rafsanjani in his killing.
