Armed assailants apparently dressed as women attacked the parliament buildings in the morning equipped with assault rifles, handguns and suicide vests, killing security guards and ordinary people before taking hostages in the upper floors of the building.
Security forces then laid siege to the parliament for several hours. Three of the gunmen were shot dead in an exchange of gunfire, while another blew himself up.
In the attack at the mausoleum, one suicide bomber blew himself up while the second one was killed in a gunfight, according to the semi-official Tasnim news agency.
The ISIS media wing, Amaq, claimed “fighters with the Islamic State” carried out the assault. It was the first time that ISIS, a Sunni Muslim group fighting Iranian-backed militias in Syria, has claimed responsibility for an attack in Iran and the choice of locations were also highly symbolic.
Iran’s Intelligence Ministry said Thursday it will soon release the names and pictures of the gunmen involved in the terrorist attacks, all of whom were killed on Wednesday, Tasnim reported.
