The 1981 assassination of then president Mohammad Ali Rajaei and former prime minister Mohammad Javad Bahonar was carried out by the anti-Iran Mojahedeen-e Khalgh terrorist Organization.
The two and several other officials had convened at the Tehran office of the Iranian prime minister in a meeting of Iran’s Supreme Defense Council when a bomb explosion ripped through the building.
Survivors recounted that an aide, identified as Massoud Kashmiri, had brought a briefcase into the conference room and then left.
Subsequent investigations revealed that Kashmiri was an MKO operative, who had infiltrated the then-prime minister’s office disguised as a state security official.
