It is also reported that the director general of the prime minister's administration (as a result of suffocation in the elevator) and an elderly woman bystander outside the building were killed.

"[7] Afterward, the interim presidential council announced five national days of mourning, and Iran's Parliament selected Ayatollah Mahdavi Kani as the next prime minister.

[10] Ann K. Reed notes that Western observers believe the People's Mujahedin of Iran (MEK) was "most likely to have been responsible for the bomb blasts of June 28 and August 30."

However, Van England notes that "the explosions were set off by insiders – the first by an accomplice working in the offices of the IRP, the second by the guard in charge of security at Prime Minister Bahonar's headquarters."

[13] The Islamic Republic of Iran identified Masoud Keshmiri (who had served as Bahonar's office secretary for a year prior to the bombing) as the perpetrator.

An official in the Prosecutor General's office said that Keshmiri had concealed his anti-government activities so well that a corpse mistaken for his was buried on 31 August with full honors as a martyr of the Islamic revolution.
