Twin attacks on the Iranian parliament and Ayatollah Khomeini’s mausoleum in the capital, Tehran, have caused a number of deaths and injuries.
The assault on the parliament building may be ongoing, with conflicting reports of a hostage situation. A suicide bomber died at the mausoleum.
Iranian officials say they have foiled a third attack.
The so-called Islamic State group (IS) has claimed it carried out the attacks, which would be a first in Iran.
IS later posted a video which showed what it claims is footage from inside the parliament building.
Gunmen armed with Kalashnikovs broke into the parliament in the morning, killing a security guard, and there are reports of several more deaths. It is unclear whether the situation has been resolved, and images from the scene show a major security operation.
There are unconfirmed reports of a continuing hostage situation, and on video filmed outside parliament heavy gunfire can be heard.
MP Mojtaba Zonnour says security forces have the streets near Iran’s parliament “under full control” but are still trying to control the situation inside the building, reports Mehr news agency.
At around 10:40 (06:10 GMT) attackers at the mausoleum in southern Tehran, which is dedicated to the Islamic Republic’s founder Ayatollah Khomeini, opened fire.
The governor of Tehran said one attacker there had detonated a suicide vest and another had been killed by security forces, state broadcaster Irib reports.
Images from the scene showed grenades and magazines for automatic weapons, apparently recovered from the body of an attacker.
There are reports that either one of the attackers was female, or possibly just dressed as a woman.
Several members of the public, visiting the shrine, have been injured.-BBC
