At least four unidentified gunmen have reportedly carried out seemingly coordinated attacks on Iran’s parliament and the shrine of revolutionary founder Ayatollah Khomeini, in which at least two people reported killed. Some people have been taken hostage by the attackers.
According to ISNA news agency, a security guard was killed when four gunmen burst into Tehran's parliament complex, while a gardener was reported dead when several armed assailants entered the grounds of Khomeini's mausoleum in the south of the city.
Though the identity and motivation of the attacker was still unclear, Iran’s state television quoted the Intelligence Ministry as saying that the twin attacks in Tehran were carried out by terrorists.
According to lawmaker Mehdi Kiaee, the situation is under control inside the parliament, while security forces are working to restore calm there, Iran’s Press TV reported.
An official at Khomeini’s mausoleum in south Tehran said "three or four" people had entered via the western entrance and opened fire, killing the gardener and wounding several people, according to the Fars news agency.
Fars said a female suicide attacker blew herself up outside the shrine and published photos showing the explosion.
Four men armed with rifles and a pistol were reported to be inside the parliamentary complex, around 20 kilometres away (12 miles) in the centre of the city.
Tasnim news agency said one of the men had later left the building and was firing in the street, but was forced back inside by police fire.
Iran, the predominant Shiite power, has been helping both Iraq and President Bashar al-Assad’s regime in Syria to battle the Sunni extremist ISIS group.
Iran’s Interior Minister Abdolrahman Fazli told ISNA he had convened a special meeting of the country's security council. Shiite Iran has been singled out as a target by jihadist groups, including IS, but has largely escaped attacks within its urban centres.
