The Kamangir bloggers write: On June, 1994, a massive blast destroyed portions of the shrine, killing twenty six people. The explosion happened in the Ashura decade, the time in each year Shias mourn for Imam Hossein's martyrdom . People's Mujahedin of Iran (PMOI), a terrorist Iranian organization based in Iraq at the time, accepted the responsibility. The guy assumed to be responsible for the blast was killed in a shooting. However, after Saeed Emmami, a high ranking official in Iranian Intelligence, was arrested and charged with assassinating opposition figures, he also confessed that his group had links to the the bombers. This event, like many others in recent Iran's history, was never fully investigated and clarified. And just out of nowhere, a group of gunmen blast a shrine, causing different religious groups in Iraq to fight together.
