On 28 June 1981, bombs were detonated at the headquarters of the since-dissolved Islamic Republic Party. Around 70 high-ranking officials, including Chief Justice Mohammad Beheshti (who was the second most powerful figure in the revolution after Ayatollah Khomeini at the time), cabinet members, and members of parliament, were killed. The PMOI never publicly confirmed or denied any responsibility for the deed, but only stated the attack was `a natural and necessary reaction to the regime's atrocities.` Khomeini did accuse them of responsibility and, according to BBC journalist Baqer Moin, the PMOI were "generally perceived as the culprits" for it in Iran. Two months later on August 30, another bomb was detonated killing President Rajai and Premier Mohammad Javad Bahonar. A member of the PMOI, Mas'ud Kashmiri, was announced as the perpetrator, and according to regime reports came close to killing the entire government including Khomeini. The reaction following both bombings was intense with thousands of arrests and hundreds of executions of PMOI and other leftist groups, but "assassinations of leading officials and active supporters of the regime by the PMOI were to continue for the next year or two."
