Voters in Iran are taking part in elections to choose the 290 members of the country's parliament, the Majlis.
It is the first poll since mass opposition protests were sparked by Mahmoud Ahmadinejad's disputed presidential election victory in 2009.
The vote is widely viewed as a contest between his supporters and those of Supreme Leader Ayatollah Ali Khamenei.
The opposition Green Movement is not taking part. Its leaders have been under house arrest since February 2011.
