ISIS attacked Iran this morning for the first time and has already claimed credit for the bombings, which killed 12 and injured 42. They bombed both the parliament and a Khomeini shrine, as well as shooting some at the shrine before they set off the bomb.
Also note that they entered the parliament dressed in burkas:
BLOOMBERG – Islamic State claimed its first attack in Iran, as suicide bombers and gunmen struck at the heart of the country’s political and religious establishment on Wednesday.
Assailants entered the parliament building in Tehran and the shrine of the Islamic Republic’s founder, Ayatollah Ruhollah Khomeini, to the south of the city.
Twelve people were killed and 42 injured in the simultaneous attacks, state-run Press TV said. Fars news agency said the two incidents, which lasted for several hours, were over.
The Sunni extremist group Islamic State claimed both attacks using its Amaq News Agency, saying they were carried out by its fighters and were its first in Iran — the Middle East’s Shiite power.
Four attackers entered parliament using the public entrance wearing women’s clothes, Tasnim cited Deputy Minister Hossein Zolfaghari as saying, and a firefight with security forces began immediately. Hours later, the Intelligence Ministry said a suicide bomb went off. At least two people were killed in the legislature, Tasnim news agency reported, and more than 30 people injured. Three militants were killed and one blew himself up.
“Several cowardly terrorists accessed the parliament’s building and were dealt with forcefully,” Parliamentary Speaker Ali Larijani said, according to Tasnim. “It shows terrorists are trying to create trouble in Iran, which is an active center in the fight against terrorism.”
In a separate incident on the outskirts of the city, gunmen entered the Khomenei shrine and opened fire before an explosion hit the site, Tasnim said. Images of the blast were shown on Press TV, which said one assailant was shot dead before he could set off his explosives, but another succeeded in detonating a bomb.
