Iran parliament hostages held separate blast at khomeini mausoleum

You're referring to a significant event in Iranian history!

On June 28, 1981, a bomb exploded at the Iranian Parliament building in Tehran, killing 72 people and injuring over 200. This attack was carried out by the Mujahedin-e Khalq (MEK), a militant opposition group that was opposed to the Islamic Republic of Iran.

Just hours later, on June 29, 1981, another bomb exploded at the mausoleum of Ayatollah Ruhollah Khomeini, the founder of the Islamic Republic of Iran, in Tehran. This attack killed 17 people and injured over 50.

The attacks were seen as a major blow to the Iranian government and a challenge to the authority of Ayatollah Khomeini. The MEK, which was once a key player in the Iranian Revolution, had become disillusioned with the Islamic Republic and was seeking to overthrow it.

The attacks led to a significant crackdown on opposition groups in Iran, and many MEK members were arrested, imprisoned, or forced to flee the country. The MEK has since been designated as a terrorist organization by several countries, including the United States.

The events of June 28-29, 1981, remain a significant part of Iranian history and politics, and are often referred to as the "Iranian Parliament and Khomeini Mausoleum bombings."
