Suicide bombers and gunmen attacked Iran’s parliament and the Mausoleum of Ayatollah Khomeini in Tehran on Wednesday morning, killing at least 12 people in a twin assault at the heart of the Islamic Republic, Iranian officials and media said.
Islamic State claimed responsibility and released a video purporting to show gunmen inside the parliament building and one body, apparently dead, on the floor.
The rare attacks were the first claimed by the hardline Sunni Muslim militant group inside in the tightly controlled Shi’ite Muslim country. Islamic State has regularly threatened Iran, one of the powers leading the fight against the militants’ forces in neighboring Iraq and, beyond that, Syria.
The raids took place at a particularly charged time after Iran’s main regional rival Saudi Arabia and other Sunni powers cut ties with Qatar on Monday, accusing it of backing Tehran and militant groups.

The incident could exacerbate tensions in Iran between newly re-elected President Hassan Rouhani, a pragmatist, and his rivals among hardline clerics and the powerful Islamic Revolutionary Guard Corps (IRGC).
Attackers dressed as women burst through parliament’s main entrance in central Tehran, deputy interior minister Mohammad Hossein Zolfaghari said, according to the semi-official Tasnim news agency.
One of them detonated a suicide vest in the parliament, he said. About five hours after the first reports, Iranian media said four people who had attacked parliament were dead and the incident was over.
At least 12 people were killed by the attackers, the head of Iran’s emergency department, Pir-Hossein Kolivand, was quoted as saying by state broadcaster IRIB.
“I was inside the parliament when shooting happened. Everyone was shocked and scared. I saw two men shooting randomly,” said one journalist at the scene, who asked not to be named.
Soon after the assault on parliament, another bomber detonated a suicide vest near the shrine of the Republic’s revered founder, Ayatollah Khomeini, a few kilometers south of the city, Zolfaghari said, according to Tasnim.
A second attacker was shot dead, he said. The shrine is a main destination for tourists and religious pilgrims.
“The terrorists had explosives strapped to them and suddenly entered the shrine and started to shoot around,” said the shrine’s overseeer, Mohammadali Ansari.
The Intelligence Ministry said security forces had arrested another “terrorist team” planning a third attack, without giving further details.
“I was shopping and suddenly heard shooting,” said housewife Maryam Saghari, 36, who lives near parliament. “People started to run away from the area. I was very scared. I don’t want to live in fear,” she told Reuters by telephone.
Television footage showed police helicopters circling over the parliament building, with snipers on its rooftop. Tasnim praised the elite Revolutionary Guards for confronting the attackers.
The Fars news agency, which is close to the Guards, blamed Iran’s arch foes, the United States and Saudi Arabia, for the attacks. It noted that they took place two weeks after U.S. President Donald Trump visited Riyadh and vowed to isolate Iran.
Iran is locked in a tussle with Saudi Arabia for regional influence which is being played out in the Yemen conflict as well as in Syria and Iraq.
“It is very likely that these attacks were coordinated. Its hardly a coincidence that it happened within minutes of each other.”
The Islamic State of Iraq and the Levant (ISIL, also known as ISIS) group claimed responsibiliy for the attack via its online forum.
“Fighters from the Islamic State (ISIL) attacked the Khomeini mausoleum and the parliament building in Tehran,” the Amaq agency said, citing a “security source”.
