The office of Mohammad Javad Bahonar, Prime Minister of Iran, was bombed on 30 August 1981 by the People's Mujahedin of Iran (MEK), killing Bahonar, President Mohammad Ali Rajai, and six other Iranian government officials. The briefcase bombing came two months after the Hafte Tir bombing, which killed over seventy senior Iranian officials, including Chief Justice Mohammad Beheshti, then Iran's second-highest official.
