Iran's Mousavi urges more protests, gunfire heard: Via Reuters.

TEHRAN (Reuters) - Iranian opposition leader Mirhossein Mousavi urged his supporters on Sunday to continue their protests over a disputed presidential election, in a direct challenge to the leadership of the Islamic Republic. EDITORS' NOTE: Reuters and other foreign media are subject to Iranian restrictions on their ability to report, film or take pictures in Tehran.

Helicopters buzzed through the evening sky over Tehran and gunfire was heard in northern Tehran, a bastion of support for the reformist former prime minister.

"Protesting against lies and fraud (in the election) is your (Iranians) right," Mousavi said in a statement on his website.

"In your protests continue to show restraint. I am expecting armed forces to avoid irreversible damage," he added.

At least 10 people were killed in a crack down on protests on Saturday and Mousavi said the deaths, and the mass arrest of his supporters, would "create a rift between society and the country's armed forces."

Mousavi's comments came the day pro-reform clerics stepped up criticism of Iran's authorities after more than a week of unprecedented popular defiance against the leadership of the Islamic Republic.

In pro-Mousavi districts of northern Tehran, supporters took to the rooftops after dusk to chant their defiance, an echo of tactics used in the 1979 Islamic revolution.

"I heard repeated shootings while people were chanting Allahu Akbar (God is greatest) in Niavaran area," said a witness, who asked not to be named.

Another witness heard shooting in Zaferaniyeh district in the north of the capital. There were no immediate reports of casualties.

The shooting appeared to be an attempt by the authorities to break up unsanctioned protests. Government restrictions prevent correspondents working for foreign media from attending protests to report.

As authorities fulminated against protesters backing Mousavi, moderate former President Mohammad Khatami signaled increased opposition among pro-reform clerics to Iran's conservative leadership.
