Armed individuals have opened fire at the Iranian parliament and the shrine of Ayatollah Khomeini in the capital, Tehran, causing a number of casualties.
Heavy gunfire could be heard on an audio recording from inside the parliament chamber, and there are reports that a security guard has died.
Several people were injured at the shrine, dedicated to the founder of the modern Islamic republic.
There was one suicide bomber and two or three other gunmen.
Blimey, they're even getting terrorist attacks in Iran now.
What do we think? Is this a terrorist attack, in the traditional sense, or a rising up against the rule of ayatollahs?
With tensions rising between the Arab and Persian worlds, could this be a Sunni attack in Iran?
