Iran's main opposition leader and defeated presidential candidate Mir-Hossein Mousavi has repeated his call for a new election, after unrest this month saw clashes between police and protesters, a reformist website reported on Saturday.

"The Green Path condemns violence, though we may suffer losses, we want political prisoners to be freed, we want guarantees for a clean [new] election, we seek freedom of expression and the press," he was quoted as saying.

In mid-August Mousavi said he will continue protesting against the disputed June 12 presidential election through a social movement called the "Green Path of Hope."

The pro-opposition Mowjcamp website reported that Mousavi on Friday met reformist cleric Mehdi Karroubi, another defeated presidential contender.

It said the pair discussed the events of November 4, a day on which Iran every year marks the storming in 1979 of the American embassy by Islamist students with an anti-US rally.
