Twin Attacks in Tehran Claimed by ISIS

On June 7, gunmen and suicide bombers attacked Iran’s parliament and late revolutionary leader Ayatollah Ruhollah Khomeini’s mausoleum. The Islamic State group, also known as ISIS or ISIL, claimed responsibility for both attacks, the first in Tehran in more than a decade. At least 17 were killed and 52 were injured, according to initial reports. Iran’s Revolutionary Guards said it held Saudi Arabia responsible for the group’s actions.

One woman and one man entered the mausoleum grounds around 10:30 A.M. local time. The woman blew herself up with an explosive vest and the man died in a firefight with security forces. Around the same time, four gunmen, reportedly disguised as women, opened fire on security guards at the visitors’ hall of parliament. They took at least four people but were killed before they could enter the office building. One attacker reportedly blew himself up on the fourth floor, according to an Interior Ministry source.

The exact details are not clear because multiple sources have given slightly different accounts of the events and aftermath. The Tehran police chief later said authorities arrested suspects. One woman was reportedly arrested at the mausoleum. The National Security Council said that the assailants were Iranian. The Intelligence Ministry confirmed that the five men had left Iran to fight for ISIS in Mosul, Iraq and Raqqa, Syria. They returned to Iran in August 2016, but fled the country after their leader, whose nom de guerre was Abu Aisha, was killed. They returned at a later point to launch the recent attacks. The six assailants who were killed were reportedly from western Iran. The woman who was captured is from southern Iran, according to Alaeddin Boroujerdi, chairman of Parliament’s National Security and Foreign Policy Committee.


ISIS claimed credit for the attack while the four-hour siege inside parliament was unfolding. “Fighters from the Islamic State attacked the shrine of Khomeini and the Iranian parliament building in the center of Tehran,” the group said in a message published by its Amaq news agency. The group also released a video from inside parliament. "Oh God, thank you... Do you think we will leave? No! We will remain, God willing," one attacker shouted. It was a slogan used by ISIS spokesman Abu Mohammad al Adnani, who was killed in Syria in 2016.


At least four of the attackers were reportedly from Paveh, a Sunni Kurdish town in Kermanshah province, western Iran. Serias Sadeghi, who was identified by the Intelligence Ministry, was a known ISIS recruiter. In 2014, a Kurdish opposition group published a report warning about increased ISIS activities in Iranian Kurdistan, including his efforts.

ISIS has recently ramped up its anti-Iran messaging. In March 2017, it released a rare Farsi-language video threatening the Islamic Republic. ISIS encouraged Sunnis living in Iran to rebel against the regime and warned that it “will conquer Iran and restore it to the Sunni Muslim nation as it was before.” Since then, ISIS has published four issues of its online magazine “Rumiyah” (Rome) in Farsi. ISIS views Shiites, who account for some 90 percent of Iran’s population, as apostates. Iran has been heavily involved in the fight against ISIS in Iraq, and to a lesser extent, Syria.


Iranian leaders downplayed the significance of the attacks. Some lawmakers even took selfies as they waited for security forces to deal with the terrorists.


Supreme Leader Ayatollah Ali Khamenei said that “the fumbling with firecrackers in Tehran won’t affect the will of the nation.” Parliamentary Speaker Ali Larijani said the terrorists were cowards and that the attacks were a “minor issue.” His fellow lawmakers responded to his remarks by shouting “Death to America.” Many Iranian leaders have accused Washington of supporting ISIS.

The attacks could have economic implications for Iran, which is still slowly recovering from years of sanctions. The Tehran Stock Exchange’s main index lost 535 points, or 0.67 percent, in the hours immediately following the attacks. The incidents follow the reelection of President Hassan Rouhani, who has promoted tourism and presented Iran as a safe and stable country in an otherwise volatile region.





Supreme Leader Ayatollah Ali Khamenei



The terrorist incidents – which occurred in our late Imam's Holy Shrine and in the Islamic Consultative Majlis (Parliament) on the 12th day of the auspicious month of Ramadan, leading to the martyrdom of a number of dear individuals, while they were fasting, and the injury of an even greater number of people – are a clear sign of the vicious grudge and enmity of arrogant mercenaries towards the dignified people of Iran, and towards everything that is related to the Revolution, to the Islamic Republic, and to its late honorable leader. Such crimes – which are suggestive of the malevolence and at the same time lowliness of the perpetrators – are too trivial to undermine the determination of the Iranian nation. The definite outcome of such a course of action is nothing but an increase in hatred towards the U.S. government and its agents in the region – the likes of Saudi Arabia.

The Iranian nation will move forward with unity and with firm determination, God willing. I wish to commemorate the martyrs of this incident, and I express my congratulations and condolences to their families. I ask Allah the Exalted to cure the injured and the casualties of this incident.

President Hassan Rouhani

“Great Iranian nation and brave men and women of this land; you have paid the price of your dignity, independence, and freedom alongside great conspiracies from savage terrors to the imposed war with sacrifice and martyrdom of your children. The insensitive, cowardly actions today by terrorist mercenaries in killing a number of innocent, fasting people near the tomb of the founder of the Islamic Republic of Iran and “House of People” is not an unexpected incident.

“About four decades after the formation of the Islamic Revolution and the crystallisation of “religious democracy”, today's Iran has realised all elements of national power. Today, Iran is the most secure country at the heart of a turbulent region thanks to the brilliant leadership of the Supreme Leader and also the authority and integrity of the security, defense, intelligence and law enforcement forces. On the other hand, people's unparalleled attendance in the elections once again proved national integrity and peoples support.

“It is natural that the enemies of the Islamic Iran do not tolerate the honours and unity between the government, administration and nation, hiring and supporting retrogressive and takfiri elements in an attempt to hide the collapse of Islamic values and dissatisfactions in their own societies, unaware of the fact that we have passed this test and the Iranian nation, which is acts based on the culture of Ashura, will prove again this time that it will shatter any conspiracy and plots by the enemies with more unity and integrity and its powerful security system.

“Without a doubt, today's terrorist attacks in Tehran will further strengthen the Islamic Iran's resolve in its combat against regional terrorism, extremism and violence more than before. Iran's message, like always, has been that terrorism is a universal problem and unity in fighting extremism, violence and terrorism with regional and international cooperation is the most important need of today's global community.

“I hereby express my condolences to the bereaved families who lost their loved ones in these terrorist attacks during the month of God's feast, asking the Almighty the highest places for the martyrs, patience and reward for the bereaved families and swift recovery for the injured.

“It is obvious that the powers, organs and security organisations will not abandon attempt until all aspects of the insensitive action and their overt and covert supporters are identified.”

“[T]hose who have aided and abetted the Daesh terror group are accomplices in twin attacks claimed by the Takfiri group.”

The timing of the attacks, which occurred soon after President Donald Trump’s meeting with “the rulers of a regional reactionary regime,” (in Saudi Arabia) indicates that “they have a hand in the bestial attacks.”

Iranian Interior Ministry

“On Wednesday, two terrorist teams simultaneously tried to conduct blind terrorist acts in the vicinity of the Mausoleum of the founder of the Islamic Republic, Imam Khomeini, and also in Iran’s Parliament.

“The first terrorist team consisted of two people who entered the Imam Khomeini Mausoleum at around 10:30 a.m. One of them blew up her vest and the second was killed in a fire exchange with security forces.

“The second team was composed of four people, who concurrently with the first team, tried to enter the administrative building of the Parliament. Facing reaction from the security forces, one of them detonated his vest and the three others were killed in a shoot-out with the police forces while trying to reach the upper floors of the parliament building.

“Based on reports, 12 people have been killed and 42 other injured in these two incidents.

“At the moment, both events are over and everything is fully under the control of security and military forces. Further news of these events will subsequently be published.

“To verify the details and exact dimensions of the two incidents, Iran’s Supreme National Security Council will hold a meeting chaired by the Interior Minister later on Wednesday.

“In order to prevent the spread of false news, it is advised that all the media outlets avoid publishing unofficial news.”
