Armed men launched two attacks in Iran on Wednesday morning, killing a guard at the parliament in central Tehran and wounding several people at the Mausoleum of Ayatollah Khomeini a few kilometers south of the city.

Lawmaker Elias Hazrati told reporters, three assailants, one with a pistol and two with AK-47 assault rifles, raided parliament.

Another lawmaker said one of the assailants was surrounded by security forces and all the doors to the building had been closed.

"I was inside the parliament when shooting happened. Everyone was shocked and scared. I saw two men shooting randomly," said one journalist at the scene.

Around half an hour later, an armed man opened fire at the Mausoleum of Ayatollah Khomeini and wounded a number of people, the semi-official Fars.

It was reported by an official at the mausoleum saying that the attacker had blown himself up after shooting at people.
