Gun attacks and suicide bomb in Tehran, at least two dead

Tehran: Gunmen and a suicide bomber have carried out apparently coordinated attacks on Iran's parliament and the tomb of founder Ruhollah Khomeini, state media said Wednesday, with at least two people reported killed.

It was not immediately clear who could be behind the attacks but Iran is a key player in efforts against the Islamic State group in both Syria and Iraq.

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, according to the ISNA news agency.

At least eight people were wounded in the attacks, according to the reports. 

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.

News agencies ISNA and Fars had earlier said three people had been shot after the gunmen entered via the north entrance, including at least one security guard.

The ILNA news agency said security forces were dismantling a bomb inside the Khomeini shrine and that firing was still going on around the site. 

It was not clear if the assailants had been able to enter the actual mausoleum. 

The city was on lockdown, with streets blocked and the metro closed, and journalists kept away from the shrine by police.

Interior Minister Abdolrahman Fazli told ISNA he had convened a special meeting of the country's security council.
