Tehran, Iran (CNN)Attackers have mounted a simultaneous assault on Iran’s parliament building and the tomb of the republic’s revolutionary founder in Tehran, state media reported.
Gunmen went on a shooting spree in the parliament, where at least one attacker detonated a suicide bomb. At the same time, a gun and bomb attack targeted the Ayatollah Khomeini mausoleum on the southern outskirts of the Iranian capital.
A woman was arrested after the attack at the tomb, the semi-official Fars news agency reports. The agency reported that another attacker has been surrounded by security officers. Two people were injured there.
The attackers were holding a number of hostages inside the highly-fortified parliament building, Press TV reported, as Iranian officials scrambled to establish who was behind the attacks or whether they were coordinated.
Attacks of this nature are extremely rare in Iran, particularly in the highly-controlled capital where tourist and government sites are tightly policed.
Gun ownership is heavily controlled in Iran, raising speculation that the attackers’ guns were smuggled into the country.
