Death toll rises to 13 in Iran twin terror attacks

"According to initial reports, the assailants opened their way into the parliament's administrative building while shooting at the guards, killing at least two [Iranian Revolutionary Guards Corps] guards and three others, and wounding 25 civilians", according to Fars.

The attacks were the first claimed by the hardline Sunni Muslim militant group in the tightly controlled Shi'ite Muslim Iran.

One worker on site was killed and several others injured in the attack on the shrine, Press TV reported, citing the Tehran governor.

Update 12.15pm: It's being reported that the Islamic State has published a video showing the attack on the Iranian parliament, which is thought to have killed at least seven people.

The Islamic State group claimed responsibility Wednesday for a stunning pair of attacks on Iran's parliament and the mausoleum of its modern founder, the first such attack claimed by the Sunni extremist group in the Shiite-ruled nation.

People gather near the parliament building during the attack.

The semi-official Tasnim news agency says medics are treating the guard.

The violence began in midmorning when assailants with Kalashnikov rifles and explosives stormed the parliament complex where a legislative session had been in progress.

It was not immediately clear who was behind the attacks or if they were coordinated.

Iranian security officials have not said who might have been behind the attacks, although state media called the assailants "terrorists".

State TV later said four attackers were involved in the parliament attack, and that eight people were wounded.

It described the attackers as "terrorists" and said one carried out a suicide bombing, without providing further details.

About a half-hour later, another group of attackers rushed the mausoleum of the Ayatollah Khomeini.

"Let us tell the people of Iran that while we have serious disagreements with them on a number of issues, that today when they are mourning, when they are dealing with the shock of a terrorist attack, today is not the day to go forward with this piece of legislation", Sen.

Attacks are rare in Tehran and other major cities though a Sunni militant group named Jundallah and its splinter group Ansar al Furqan have been waging a deadly insurgency, mostly in more remote areas, for nearly a decade.

"We grieve and pray for the innocent victims of the terrorist attacks in Iran, and for the Iranian people, who are going through such challenging times", he said in the two-sentence statement.
