SAVAGE ATTACK: Opposition supporters beat up policemen during clashes in central Tehran on Sunday. (Reuters)   TEHRAN: Iranian security forces on Sunday killed at least five people, including a nephew of opposition leader Mir Hossein Mousavi, during the fiercest clashes with anti-government protesters in months, state television and witnesses said. English language Press TV said Mousavi's 35-year-old nephew Ali Mousavi was killed by "unknown assailants." Amateur video footage purportedly from the center of Tehran showed an enraged crowd carrying away one of the casualties, chanting, "I'll kill, I'll kill the one who killed my brother." In several locations in the center of the capital, demonstrators fought back furiously against security forces, hurling stones and setting their motorcycles, cars and vans ablaze, according to video footage and websites. Demonstrations also took place in at least three other cities. A close aide to Mousavi, a presidential contender in a disputed June election, said Ali Mousavi, died of injuries in a Tehran hospital. Mousavi's website and another reformist website, Parlemannews.ir, also said Ali Mousavi died during clashes in which security forces reportedly fired on demonstrators. The protesters in Tehran tried to cut off roads with burning barricades that filled the sky with billowing black smoke. One police officer was photographed with blood streaming down his face after he was set upon by the crowd in a blazing street.
