TEHRAN, Sept 5(AP/UNB) - Iran's elite Revolutionary Guard has condemned an attack on the home of an opposition leader, calling the perpetrators "unruly elements."

The state news agency on Sunday quoted the Guard division in Tehran as saying the attack on Mahdi Karroubi's home was caused by "unruly elements" and the Guards "strongly condemn it."

The statement added that the group was "totally unrelated to the Guards and Basij," it said referring to the group's street militia.

On Thursday a large group of men attacked the home of Karroubi and beat one of his bodyguards unconscious.

The opposition has accused the Basij of being behind the attack. Karroubi was one of the pro-reform candidates who ran against President Mahmoud Ahmadinejad in June 2009 election and said the contests were fraudulent.
