On 28 June 1981, bombs set by the MeK killed 70 high-ranking officials of the Islamic Republic Party, including Chief Justice Mohammad Beheshti who was the second highest official after Ayatollah Khomeini at the time. Two years after the Islamic Revolution of Iran, the MeK detonated bombs at the headquarters of the now-dissolved Islamic Republic Party. Two months later, the MeK detonated another bomb in the office of the president, killing President Rajai and Premier Mohammad Javad Bahonar. Their attacks did not succeed in overthrowing the Islamic Republic of Iran government.
