During that time, Mohammad-Ali Rajai was president and Mohammad-Javad Bahonar was prime minister.
On August 30, 1981, President Rajai held a meeting of Iran's Supreme Defense Council, along with Prime Minister Mohammad Javad Bahonar.
Witnesses later stated that a trusted aide brought a briefcase into the conference room, setting it between the two leaders, then left.
Another person opened the case, triggering a bomb that set the room ablaze and killed Rajai, Bahonar, and three others.
After Mohammad Beheshti was assassinated on June 28, 1981, Bahonar became the secretary-general of the Islamic Republic party, but he didn't last long in that position, nor in the position of Prime Minister, as he was assassinated after less than two months in these offices, along with Rajai and other party leaders, when a bomb exploded at his office in Tehran.
