TEHRAN (AFP) - Iran police clashed with stone-throwing protesters after the funeral attended by vast crowds of mourners in the holy city of Qom on Monday of dissident cleric Ayatollah Hossein Ali Montazeri, websites said. Montazeri, an inspiration to reformists and human rights activists and a fierce critic of the clerical regime he helped create, died aged 87 on Saturday. Opposition websites said hundreds of thousands of mourners poured onto the streets of Qom, many chanting slogans and displaying the green of Irans opposition effectively turning the funeral procession into a massive anti-government rally. Mourners were shouting slogans such as Dictator, Montazeris way will continue and Montazeri is not dead, it is the government which is dead, opposition website Rahesabz.net said. A report on the parliaments reformist minority faction website Parlemannews.ir said that shots were heard fired into the air at the shrine of Masoumeh where Montazeri was buried. The report was titled margins of the funeral and did not offer any details on when the incident had happened. Another website, Kaleme.org, said police and security forces clashed with a groups of chanting mourners who after the funeral had gathered in front of Montazeris house. The police cracked down on people who were shouting (anti-government) slogans in front his house and people threw stones at them, the website said. Hundreds of basij militia members and clerics, it added, also gathered near Montazeris house and chanted slogans in favour of Irans supreme leader Ayatollah Ali Khamenei and against the protesters. Rahesabz.net said a group of basijis attacked Montazeris house and tore up his funeral banners. There were no immediate reports of injuries or arrests. Opposition leaders Mir Hossein Mousavi and Mehdi Karroubi attended the funeral ceremony, which was marred by brief clashes between hardline pro-government vigilantes and mourners, reports said. The reports could not be independently verified by AFP as foreign media are banned from covering the ceremony. Crowd estimates could also not be verified, with a conservative news site Asriran.com also reporting hundreds of thousands of mourners at the ceremony. The cleric, who had been considered by his followers as the highest living authority of Shia Islam in Iran, was buried in the shrine of Masoumeh, a revered Shia figure. Irans Nobel peace laureate Shirin Ebadi described him as the father of human rights and herself one of the millions of his followers and students in a statement on Rahesabz. I learned from you that the silence of the oppressed is aiding the oppressor and that I should not remain quiet, the lawyer and rights activist said. A White House spokesman also expressed condolences on the passing of the cleric, even though Iran and the United States have had no diplomatic ties for three decades. Our thoughts and prayers are with his family and those who
