Suicide bombers and gunmen attacked the Iranian parliament and Ayatollah Khomeini’s mausoleum in Tehran on Wednesday, killing at least 17 people in an unprecedented assault that Iran’s Revolutionary Guards blamed on regional rival Saudi Arabia.
Islamic State claimed responsibility and threatened more attacks against Iran’s majority Shi’ite population, seen by the hardline Sunni militants as heretics.
Iranian Foreign Minister Javad Zarif tweeted: “Terror-sponsoring despots threaten to bring the fight to our homeland. Proxies attack what their masters despise most: the seat of democracy.”
He did not explicitly blame any country but the tweet appeared to refer to comments made by Saudi Arabia’s deputy crown prince, Mohammed bin Salman al-Saud, in May, saying that that Riyadh would bring “the battle” for regional influence to Iran.
